what if I get lonely but I can't stand people?

I'm 36 a single woman, own my own home have had a steady job for 9 years now at the county. I also have had two sons that the fathers both left me to raise them by myself, while they went off and married other women. So yes, I am very independent but I have to be honest and say it was not my choice in the beginning. Many men and people have used me and took advantage of my niceness and hurt me. Now I have a very hard time connecting with people and trusting them. I always feel like they're kind of annoying, or they don't really like me and they're plotting against me, or they just don't get what I'm talking about half the time. I get really lonely and I want to have a boyfriend and friends, but I just can't handle being around people.
