I feel totally alone and i'm only 35! Anyone else feel the same?

I was put in care when i was 5 and it's mainly because of this that i have moved about 30 times in my life. I split with my last girlfriend 6 years ago and have really struggled to find a new partner. I have tried every dating website your can think of, tried speed dating the lot. I would admit that i am a bit fussy, but we all want to meet the right person don't we? Looking back, i've always been a bit of a loner. I find conversations with people i don't know hard work and yet i do this professionally every day as i work at a hotel. I find social situations difficult. I have low confidence and self esteem. I see myself as the most boring person i know. I'm mr average. What would anyone special see in me. With this outlook i have no chance. I've read books on confidence building, been to see a counsellor etc. Nothing seems to work. I spend my days off sleeping and feeling miserable. There must be lots of people who are in the same situation. What happens to people like us?
