Do you want to compare lives? Were you molested at the age of five, going on for many years? I was. Were you raped? I was. Did both your parents die within 6 months of each other? Mine did.
I've been where you are and worse. Guess what, I didn't care either.
The one thing I had going for me were the best two parents any child could have.
I got help to deal with my past, and I got help to stop trying to destroy myself. Now I'm married, have two great kids, pets galore, a home of my own, and a wonderful husband that's also my best friend.
If I had given up, like you seem to be doing, I wouldn't have any of this. I'd most likely be living on the streets or I'd be dead. That's the reality.
You have control over your own life. You don't seem to be as weak as you sound. Do you have strength in you? I think you do. So stop fighting against everyone that cares about you and start fighting for yourself! Fight to be a better person and fix the crap you think isn't fixable, because I can tell you right now, no matter how bad you think your life is, someone has it worse. You have a mom that cares about you, and from what you said, you care about her too. So stop feeling sorry for yourself and do something about it!
Yes, that's a double dare. Get help, you need it. You'll be amazed what therapy can do for you, that and some self respect.
