For what it's worth, I'd date you. You sound like an exceptionally kind and decent woman. The girl I'm seeing now has also been through abuse and that has made it hard for her to trust people too. I am very grateful that she was brave enough to give me a chance. You sound very brave too. In spite of everything, you have the courage to start conversations with boys. This is such a rare occurrence in my experience, and those guys clearly can't appreciate the wonderful opportunity they've been given to actually have a conversation initiated by a girl.
You say you have friends who are in relationships. Well if they are true friends then they'll help you find a relationship of your own, provided they know about your troubles. If they don't, then tell them you'd like their help. I know that can be hard, and it's always better when friends help each other out spontaneously. But in any case, at least make sure they know how much you need them.
Also, I would advise you to try online dating. There is no shame in that, despite what some jerks would have you believe. You can skip past all the bull crap and know right from the start that every man you look at is interested in finding a woman to be with. And you won't even have to start the conversations if you don't want to. You will most likely be messaged every day. The biggest free dating sites are plentyoffish and okcupid.
