I have felt like you all my life - at school, uni, work, when my DCs were growing up - up until a year ago, that is.
I'm now in my 40s and decided a couple of years ago to start joining things as I didn't have a partner, social life or friends. I just joined any groups etc that I heard about - not all worked out, but some did - Meetup groups and dancing being the best.
Through involving myself in various activities I seemed to relax and not take everything, including myself, so seriously. Nothing was a big deal anymore. I found that as I changed, people's attitudes towards me changed. They were friendly and welcoming towards me. I became part of their group! They invite me to their parties! I have friends! I have a social life!
I don't feel that I'm particularly behaving any differently to how I used to but I know there is something about me now that people like,when previously I think I must have given off negative vibes,
Last week the father of a lad who used to be friends with my DS years ago came up to me in the supermarket and said 'hello' - I hadn't even noticed him. He wanted to chat to me - asked me about my DC etc. Yet he was someone i previosly viewed as someone who would never deem to pass the time of day with me. Now he wanted to chat!
I'm not totoally sure what's happened to me although i now realise that I use better posture, look ahead rather than down and smile more, but i think its more to do with what's going on inside - how I feel about myself - thats changed. I know I'm different because people's responses tell me so.
