What a fabulous thread. Probably the best ever on the internet so thanks OP.
I identify so much with what so many of you are saying.
Looking back I was a very shy and reserved child and highly anxious - growing up in a violent, alcohol based environment coupled with a fear inducing Roman Catholic education did not help much I guess.
Performance anxiety has blighted my life and prevented me from achieving anything of great worth. I have managed to remain in work all my life, despite this horrible anxiety and bouts of depression.
I work on my own now and though it is a physical job, it is undemanding in that I know what I am doing and am good at it. I meet people but once my job is done, I can leave, with no worries.
I am highly sensitive to atmospheres and take on feelings of guilt as if I am somehow to blame for whatever is going on. If anything goes missing, I feel guilty!
I too sought relief from my teens onwards in alcohol and "speed" to assume another identity and to be able to cope with relationships and sexual intimachy though of course these took me further away from any such thing.
I have had loads of unsuitable partners who are in worse shape than myself. Lame ducks or psychopaths. Eventually I became pregnant and being a single mother responsible for another human being was the making of me.
I have so many anxieties and phobias it would take ages to list them!
It was only after I came to the conclusion that I must face being alone, that I finally found out who I was and learned to cherish and love my alone time.
As I sit here typing, the washing machine is on, but there is no radio, tv or music blaring out and I love it.
I do have a partner but we do not live together. He has lived alone for some time too so I think he has these traits too. We love being together but I can sense he wants to get back to being "him" too.
The only advantage I can see in us coupling up is financial and it may have to come to that, but I fear it greatly.
Just to add, that I still have a son living at home so I am not completely alone but I love being alone, musing, just being and pottering.
Hate going out, except maybe to the theatre or a meal. the thougt of going to a pub or club brings me out in a cold sweat. I find small talk irritating and love one on one conversations. As soon as another enters the scene I feel a bit uncomfortable.
Could go on but I think that's quite enough. Reading this thread has released me from my sense of being rather aloof and strange that I prefer a book and my cat to socialising!
