Not all your problems are your fault, but they are your responsibility to deal with. That's the first thing I learned when I was in rehab. It's not my fault I'm an addict, that's a disease that's entirely out of my control. It's not my fault I'm schizophrenic. But it is my responsibility to manage the issues that arise with those conditions.

In the same vain, it's not necessarily your fault that you have a hard time socializing with other people, but it is your responsibility to manage those issues.
