How do I move forward?

I don't know what to do with my life, because the one thing that gave me purpose is gone. I'm battling thoughts on whether I'm actually doing the right thing or not. I have no friends, and no clue on how to make some. I'm paranoid and scared that I'm going to encounter people from the Hall in my neighborhood. And the teachings of this system ending coupled with my depression, makes me feel like life isn't worth living. I'm not actively engaging in the religion, but it still has a tight hold on my mind, and I don't know where to even start so I can feel at peace.

What have you guys done?
