Hapless i am sorry for what happened, but you need to realize one thing here. Being depressed isn't helping anyone, especially you.
And i am glad to hear that you are trying to help out the girl, and that is what you should do.
All these im sorry, and it sucks happened posts aren't helping for shit.
What you needed to hear was that you need to pull your head up again, get out of the ditch you were in, and help the girl and yourself.
In reality, some people think we can help you, but we cant. WE cant do jack, all the help you need is the help you can give yourself.
If you really love this girl as much as you say, you WILL find a way to help her, you have to.
The thing that happened to her, it could have happened to anyone, hell a car could hit you the next day, that's how life is, you never know what will happen or when, but since it happened to her, its up to you to help (not try, help) her, or just sit there and do nothing.
Every person has gone trough something that makes them feel really depressed, but it all depends on how they went trough that time of their life.
Now i trust that you will make the right choice later on, it looks like you have started to make it already.
Also for the people arguing on this post, this is a post to try and help hapless, not a place to bitch on someones post.
And if anyone asks why i said something like this.
It's because he needed to hear it.
