I actually snorted at the "comparison" comment - no shit Sherlock! How helpful to reply with a single clichè. You may as well say "cheer up" and dust your hands off thinking you've solved it 
Gubler sorry you feel shit. Is it coming up to the anniversary of you being ill or any other date which is making it worse, or is just a build up of everything?
I've had something similar (not meningitis but brain issue and after affects) and as PP said, the only thing that has helped really has been time - and having a supportive DH. It's been so hard thinking how my life changed drastically without warning and I think it makes you feel vulnerable and that you took stuff for granted - that might just be me?! And your life feels kind of...diminished.
Do you think there could be an element of "anger" at yourself and you're just turning it out externally? It's so easy to think "it's so fucking unfair they're off on holiday again" when we really are thinking "it's so fucking unfair I can't book a holiday with money that I've earned myself and this is how my life is". It is shit and it is depressing and there is no harm in saying so, IMO, it's acknowledgement not self pity (although there can be a fine line
)
In practical terms, I hope you get the PIP, I know people who have had problems so if you have a charity dealing with your condition they may be a good port of call. If you're used to having a job it's hard to go to not having that as an anchor. One thing that has helped me is having (the MN favourite
) hobbys (or is it hobbies? Prime example of how my faulty brain enrages me, I used to know this sort of stuff!) I've had to alter my activies, eg started with magazines instead of long books but still get enjoyment. I could go on and on here but things like this really help to fill the time which goes so slowly some days.
I also struggled with the lack of earning (and associated shitshow of houseful finances) and buy and sell little bits of eBay. Not a business and pin money but it helps. I have to accept everything takes so much longer to do too
I also learnt that it helps to talk (and moan) which I never used to do really. I still bottle stuff up to a certain extent and it doesn't help. I hope this thread has been helpful, even just knowing other people feel like this and we aren't awful human beings - we are having normal reactions to shit situations.
If there are charities or forums for people with similar conditions it may be helpful, I'm probably teaching you to suck eggs! Sorry if I am. I also hope I'm not being patronising or unhelpful, I still struggle a lot with stuff myself.
PS I also feel your pain with the LPs, I've been known to refuse them and had to be coaxed
one consultant absolutely nailed one for me, and I ask for him now. Some are definitely better than others.
