Dealing With Emotional Scars

What is the best way to deal with emotional scars? I figured this would be the best place to ask.

I've tried isolating myself form society. I've spent the last three years mostly in my apartment. While I've been able to take it easy and live a relaxing lifestyle, I've also become more and more disconnected from human society. I think it would take an external intervention now to get me to reintegrate. I wonder what I'm going to do when I run out of money? Perhaps I'll become homeless.
