I don't know what to do

ok...I dont' know what to do. One of my best friends cut and she over doses at least once a week. She doesn't take something that can really kill her but its just the fact that it makes her feel better. I'm the only one that knows this...well, her family...

does to but they don't care about her one bit and just tell her why would you do this to our family. they don't do a thing about it.
Then my other best friend is going through a real hard time and she has been admitted into the psych ward and I just want to be there for her but I don't know whats going on or what to do to help her. I wouldn do anything to help her but I don't want to push my limits. I just feel lost and want to help and I don't know what to do
I am slowly over coming anorexia and my weights fine now but I absolutely hate myself. I cut...hips, thighs...wrists. My mom saw the first cut but I promised to never do it again so she doesn't know about all the other times. I over dose...I try to kill myself. I alwasy end up just throwing up so my parents don't suspect anything. they jut think its a little flu or something. but thats been going on since june so not too long.
I'm just lost and confused and I hate myself and I don't know what to do. I don't know how to help my friends or what to do. I justy don't know how to help or be there for them or anything.

Hello,

Just want to say, that you sound just like I was at one time in my life. You feel alone. And that hurts. But what you will realise later, is that the only person you can depend on to make you happy...is you,your mind, your thoughts, your acts in life.Find your purpose, and you will find peace.Do something else that makes you feel better, other than cutting yourself. be creative. Use your surroundings to create something beautiful. Do something good for someone else. Find comfort in what you can do for others, and this in turn, will help you feel better about yourself, not to mention, you may gain more friends, and not feel as lonely.
As for your friend...he or she needs to find their own way. Listening is important, and if you feel this person will seriously hurt themself, do the right thing, you know what that is already. You don't need someone to tell you. And please, please, don't waste the gifts that you yourself could bring the world.

If you are a true friend, you will not stop until you find her help - meet with a professional where you can explain about your friends to come up with the best course of action - they are in trouble !!
