I was going to say I'm just like you, 'finally Im not the only one like me' lol but then I noticed your statement 'i know loads of people' as the other posters say too.
but....
I dont know many people at all, my day to day existance as I call it is going home in Cornwall in quiet tiny little village where I dont know anyone, to work Plymouth where a work with hardly anyone.
The village where I village is full of rich people who all seem quiet and unsocial not that I am the type to want to chat all the time and go round there house for wine and them round to mine. I rent there too which I dont feel helps, people dont seem to make the effort with renter's thinking they will move in 6 months and it a waste of time. Also most the people are middle aged to elderly so I dont think they think they have anything in common with me 27.
I work with my boyfriend (of 6-7 yrs) who I live with also, I dont drive so all I do is go from home to work 5 days a week to a office where we work alone and talk business on the phone we rarely meet anyone. We dont do holidays or social events due to the boyfriend sweight issues at 20+ stone he is worried about what people think of him and I respect his decision and help him with his feelings and diet long term. He started to put weight on when I met him and piled it on ever since due to the stressful business we own togther . As I result I havent really been out and had fun socially for 6-7yrs.
I really want to get out but my phobia of driving and living in the counrty doesnt really help me get out and there is no public transport. I really do feel social but I also worry that the lack of social environments over the years is effecting me and turning me into a hermit more and more everyday.
