@He1h I have read all of your posts, and only some of the others, so I hope that I don't keep on repeating what others have already said to you - apologies if I do!
OP you pretty much have to be born a psychopath to be a pschopath, so you can stop wondering whether you are or not, because from what you have told us about how you were as a child, you are definitely not a psychopath.
There is actually a name for the condition you are suffering from - and yes, I do believe that you are actually suffering. Unfortunately, due to my age - middle sixties - my ill health and my disabilities, and the amount of tablets I take every day - over 30 tablets a day - I cannot remember the name of the condition I am referring to, so to put it simply I will call it
"Life fatigue". A great many of us will suffer from this "Life Fatigue", and how much we suffer from it depends on many different criteria. One of the main things to affect us is how strong we are mentally, which again will depend on many different things in our lives eg: were both of our parents mentally healthy and strong, or their parents etc, as our DNA can be affected to a certain extent by our ancesters own mental health issues. In other words our own DNA is not just influenced by physical attributes.
I suppose that this often inconclusive area comes under that well known phrase, about whether certain aspects of our personalities are caused by nature or nurture? To which the answer often appears to be "both", to a lesser or greater degree, depending on any individuals personal background. I cannot explain all that I mean here, as it would need an academic thesis to even attempt it, and neither me or any Mumsnetters are up to suffering from any attempt I might make in that direction! Anyway, I am pretty sure that you, OP, and anyone else, who has had the stamina to stay with me so far, can fill in most of the blanks about how different childhood, and adulthood experiences, can and do affect how we end up being able to deal with all the shit life seems to like to throw at us.
I think that your resilience has probanly been beaten so low over the years OP, that you are indeed suffering from
"Life Fatigue", and I am so sorry that that is the case. PTSD comes under the umbrella of "Life Fatigue", and although you might not be suffering from any of the well known symptoms, such as flash backs, and/or terrible nightmares, I do believe that you might be suffering from a much more difficult to diagnose type of PTSD. Most of the well known reasons for aquiring PTSD, such as under war conditions, or a horrific accident, or suffering from a terrible assault by some low-life criminal, are already well documented, although very unfortunately, the correct care for such sufferers is often woefully under provided. The type of PTSD that I believe you may be suffering from OP is a much more insidious beast, but if left long enough, and with no treatment, it can become just as life threatening - in that too many people who have a PTSD diagnosis, but no adequate treatment, end up suicidal, or at least putting themselves at risk of very harmful behaviours - as the worst acute PTSD's sufferers.
From what you have shared with us here He1h, I don't think you are anywhere near being suicidal, as you also have some wonderful things happening in your life, like your dear small child, and you are probably being kept too busy to actually spend too much time dwelling on how you are really feeling. But that can change, and sometimes it is only what many people would consider a minor negative change, like another well known saying "the straw that broke the camel's back", that sends someone into a free-fall spiral drop. Hopefully, that just wouldn't ever happen to you OP, but I urge you to speak to your GP canidly about your increasingly unusual thoughts and behaviours, and to then - again hopefully - engage with the type of mental health counsellor that s/he recommends.
I have two more things to add, and I hope this bit is seen by all the people who have given the OP a hard time about the fact that when there is no queue for an accessible toilet/baby change, but there is a person in a wheelchair obviously heading for it, and the OP with her young child heading for it at the same time, in order to change her little ones nappy, she will speed up a bit so that she can get there first. I want to say that I can't really blame anyone for doing that, and that the biggest fault lies with the company - often a largish retail shop - for not providing seperate wheelchair and baby changing facilities. Motorway services are often guilty of the same thing. They want as much space as possible to sell their products, and are, therefore, very greedily, not willing to give up a little extra space in order to have seperate facilities for parents of young children, and wheelchair users. So, as a full-time wheelchair user myself, it is the companies that I hold the most to blame!
I have been a young, fit and healthy mum, in the days when nappy changing facilities were quite a rare phenomenon, and have changed, countless times, a small baby on a brought with me, tiny changing mat, on the floor of a grubby ladies toilet, or when even that wasn't available, in a tiny corner behind some clothes rails... So I know both the strong desire to use a proper changing table, and the sometimes urgent need to use the provided accessible toilet.
However, if anyone has ever been just behind me in the queue for a joint nappy change/accessible toilet, they have my utmost sympathy! My DH is my carer (this is relevant), and I unfortunately need him in the accessible toilet with me - I won't go into details - and it can take literally ages for me to use the toilet, even just for a wee, and my DH also has to use that toilet as I cannot be left on my own while he uses the gents toilet, so we can easily be in there for 20, or even 30 minutes! If a mum can change her baby relatively quickly, I would much rather she went into the toilet ahead of me! As I know my own disability, and I know my own bladder, I try to go to the toilet before it becomes urgent. However, to be prepared for the occassions when I am practically bursting, I am always sitting on a washable inco - incontinent - sheet, and I have at least one change of lower body clothes with me. Hopefully, most other disabled people who have my sort of bladder or bowel problems, will be similarly prepared. I also only leave the house on rare occassions, as going out, even for a few hours, is such a mammoth task, and I also don't want to be a nuisance to the general public.
One very last thing @He1h, from all that you have said up until me starting this essay, quite a while ago now, I think you are a lovely lady, who is both empathetic, and kind, but who is struggling at the moment with that very unpredictable thing, called life. Please ask for help 💐 xx
