Thank you for the replies. I do appreciate the time you've all taken to answer and help me.
I'm trying to get my head around a few of the replies but I'm struggling a bit with explaining things. I recognise some of what you've said, from my younger past-self, and I've tried really hard to change things, change myself and get beyond whatever it is that seems to hold me back. I'm in a difficult 'phase' that just seems to be unending and all of the suggestions about doing something I enjoy, trying to get out and do things to connect with other people who enjoy the same things, try and find like minded people to connect with - I've done all of those things and I think my realisation over the past few months is that they all ended in a similar way. Things I enjoyed, with the people who shared those interests, all ending up with me being dumped for someone else i.e. music/gigs/theatre/sports/study/parenting etc.
I do bore myself, and I'm not overly keen on my own company if I'm honest, but I'm a lot less stressed and uptight if I'm on my own than if I'm in company. But I don't really dislike myself either. I'm not a bad person, I'm not cruel or nasty, not rude or ignorant. I've always been the person others came to for help/guidance etc. and the one thing I've always been good at is working through problems and helping others figure things out - but as soon as I've served my purpose it's like I don't exist. And God forbid I need that help from anyone else myself. And that so hurtful for me, knowing how much I've tried for others when they have clearly just used me for their own ends. I do struggle with the positive thinking though - it seems like I struggle with the balance in my ego too - I shy away from telling myself I'm special/worthwhile/important or whatever as whenever I've tried that in the past it comes across, I think, to others that I'm over confident or my confidence doesn't match the reality of what they see IYSWIM. I've long since stopped apologising for being me, and I no longer do that overcompensating thing mentioned, which I was certainly guilty of when younger. But I still can't find that 'thing' that means other people respond to my efforts in a way that gets me somewhere.
I've had counselling and that helped me get past the problem I used to have with feeling that there was something wrong with me because some people disliked me - really disliked me - and I came to terms with the fact I don't have to try with everyone, and it's ok that not everyone likes me. So I've really tried hard to get to grips with my self esteem and anxiety over social interaction and friendships etc. I think it's just recently hit me just how bloody hard this is, constantly, and I'm just weary of keeping on trying and getting absolutely nowhere.
My personal situation makes things difficult to do more - I've been in dire financial straights for about 8 years and that's limited my choices. I'm a lone parent with little support, which again limits my opportunities to do things where I may get the opportunity to meet new people. I know that won't last forever and things are heading in the direction of getting better in the near future so I should be able to feel positive about that, but I'm just not feeling it right now because my past history tells me that even when I don't have these barriers, I'm actually no better off friendship wise. I'm aware of these things, which is why I think I find the whole work scenario so draining because my whole adult life, my social interactions/connections stemmed from work & to get to this point and realise just how little impact I make in the situation I face every day is really soul destroying.
I know I've no choice but to keep trying but right now I feel like crawling under my duvet and never getting back out. I just hate having to deal with this every single day. The breadth of how much this has impacted me over the years was so clear last night, and the realisation that school friends, work friends, family, all ended up shitting on me from a great height at some point over the years, has really hit me hard. And me being so spectacularly dim, I didn't see it at the time with a lot of them. I've been excluded from family 'gatherings', ignored by various friendship groups I tried with over the years in various settings - new mums, school mums, work friends, old friends. All scarily similar in how they've 'dumped' me despite my efforts to keep up the connection. I think that what makes the thought of trying all over again so depressing, knowing that the likelihood of a repeat seems so certain, why bother? Which is self defeating and self pitying I know, but I'm really struggling to summon the energy to try again.
