I'm not sure what I can say about this that will help you. I've got trust issues as well and I've had my attempts to get over them. If you want, I'd gladly talk to you about this. Maybe I could help some, even. And it is a good thing that you've figured out why you have this problem. Now you can fix it or work around it or do something about it. And trust me, something can be done about everything, although it will take a lot of work and time.
And for college... if you go to ones near Boston, you'll definitely have someone there to help you find additional friends to the ones you already have.
