James,
We know you have been through alot. Can you just take some moment and think? talk to yourself.
1) What had happened to you had already happened. You can't change it, you can't turn back time. Its bad memories in the the past and that you can't change. However, you have control of your future. You can create it with beautiful memories. DO YOU KNOW THAT YOUR LIVING AND THINKING ABOUT THE PAST CAUSED YOU TO BE UNABLE TO CREATE A FUTURE? Sometimes memories flashed you back to what happened. You can handle it either way. Either you continue to look at it and pity yourself or you tell yourself you deserved better and strive for a better living.
2) Since it hurts so badly, why do you want to continue in this state? why don't you do something about it? Staying in this state will not change anything, you will just continue to feel worst. Why don't you open yourself up to your community, like join some activities, get to know more friends. Its not as bad as you think, if others can have friends, so can you.
3) Can you please dont commit suicide? (not talking about hell or anything). You have the power to influence the people around you. Think about yourself in coffin (be it by suicide or old age) and someone speaks about you. Do you want them to say "I dont know why he did it, I dont even know him much" or you want them to say " he was a great friend, I will really miss him so much. We go for drinks together etc etc.".It just take one "hi" to be friends.
The world is so big, there is so many people, so many things to do, there are beautiful stuffs all around, you are able bodied, you can do anything you want. But yet...suicide. Isn't it going to be a pity?
