What to do, what to do ..

Lately, it has been getting really difficult, my mistakes that I have made, that are in my past, are coming back to haunt me. I have changed a lot in the past year, I don't deal with peoples shit anymore, and I have made less mistakes. But the memories won't leave. I am so hurt and crushed that I can't do right anymore, its really hard to think of what is wrong and right. I need a boost of energy. I need help. I'm hurting the one that deserves it least. I can't do it anymore. I need to let go, but it would hurt to much. I need to do something, because where I am right now, is not okay..
