Okay.
I can see why you do these things but I don't think you really want to be depressed all the time.

I really think that you are a strong and determined person so I know you can get out of this.
Stop the starvation, cutting and excessive drinking (especially on an empty stomach) and start eating normally again, go out with friends and enjoy life.
You probably only feel more depressed and more likely to crack because you do depressing things like drink, starve and cut.

Try to stay positive, quit those things and start being healthy again. You will feel a lot better. You honestly will...

Hope this helps.
Oh and btw. How are you today? What are you up to?
