loneliness

hi, I am new to this forum but just wondered if anyone else is in the same position as me. I am a 28 years old female. I am undiagnosed officially but had a non official assessment at my university and was told it is highly likely I have aspergers. I struggle to make and maintain friendships, more recently I have just given up completely trying to socialise or fit in. I am happily married but apart from my husband I don’t really see or speak to anyone else outside of work. I always seem to say the wrong thing and the fear of doing so has led me to stop trying to talk to people at all. I do work and just about manage with day to day small talk but I don’t make an effort to chat with people about anything unrelated to work. Recently I have been feeling very lonely and wish I had some friends to share things with, spend time with. I feel like I have no one I could turn to in a crisis except my family who all live far away. I see other people in coffee shops with their friends chatting and laughing and I just wish I could be like that. I have no idea where or how to meet friends any more. I used to be better when I was younger and especially at university where most social situations involved alcohol although I still made a lot of mistakes and faux pas which meant I never really had a lot of friends. I have had a lot of bad experiences with friends who have ended up cutting me out of their lives for one reason or another. I don’t think I am a nasty or bad person I just don’t know how to behave in social situations. The more I avoid it the worse I seem to get. Any advice or anyone in a similar position would be appreciated
