Had a tough time the last few years, a traumatic event followed by PTSD and depression, I'm improving now but have ended up very isolated and have lost all my confidence. Started taking DD to a new activity recently and kind of hit it off with one of the other mums, there's limited chance to talk so it's been quite low key but I like her and can see us being friends and I get the impression she feels the same.
All good you would think, except now the activity has broken up for summer and she's messaged me asking about meeting up over the holiday and it's put me into this ridiculous flat spin! I know it's no big deal, a perfectly normal thing to do and it's me with the problem but it's just made me want to run away and hide 
I have become so socially awkward and I don't quite know how it happened, think it's made worse by the fact that all my 'friends' pretty much deserted me when I was at my lowest and the only new friendship I've pursued since then screwed me over and then ghosted me so my trust in people is zilch. I'm scared, stupid as that sounds. Scared she'll realise I'm a socially inept fuck up and then it will just be awkward at the activity, and scared I'll let her in and then she'll betray me.
It's actually really upset me that I've reacted like this to such a trivial, normal thing and it's making me feel that maybe I've not come as far as I thought. Not sure whether I want people to agree I'm being ridiculous and give me a talking to or whether I need someone to say they can understand why I'm feeling like this and help me unpick it but I'm going round in circles with it on my own.
