What can we do to help our friend??? I need help urgently.?

So my friend has been a tomboy her whole life. But somehow her parents don't understand and have tried to force her to be girly. They say she has to have a purse every time she leaves the house and she has to wear atleast some makeup. Just recently, she has come to terms on her sexuality. She told us she thought of suicide during the time she was trying to figure out what she was. She found she was bi and had a gf for a few months. Her parents found out about a month ago that she had a girlfriend and being who they are, have sent her to counciling for thinking about her hurting her self and about being bi. However, she hasn't tried hurting herself since. Her parents have cut off contact with her now ex-gf (which is only ex because her parents made them break up). Oh, and her parents even decided it was a great idea to tell the other girls parents that their daughter was lesbian. My friend has been greatly impacted with the way her parents are handling this. They have cut off her wifi at a certain time, took up electronics including her cell phone, and are not letting her hang with her other friends like me. She also has recieved not so great of grades this past year and now are calling her a screw up. She told me her mom is crying over how her daughter is a "screw up". My friend is wanting to run away and I want to try with all my power to stop her. I don't want her to leave. Neither does my other friend. What do you think we should do to try to better the situation?? My other friend and I are thinking about telling her parents that they need to realize they are hurting their daughter more than they think and that she won't be in their lives later on. Is that a good plan? Pleasee help. :\

HAVING A DISCUSSION WITH HER PARENTS IS A GREAT IDEA, BUT IF HER PARENTS WILL NOT LISTEN TO THEIR OWN DAUGHTER, THEY ARE NOT GOING TO LISTEN TO YOU GIRLS EITHER.
Try this:  Both of you girls need to get both sets of your parents together and have the discussion. Let them know all the facts and how scared the two of you are for your friend. Ask your parents to please intervene for the safety and wellbeing of your friend.
You sound like a very caring and kind friend, most friends won't go this far to help one of the girls.
Please stay just the way you are. GOOD LUCK

Parents need to except their kids for who they are and love them for that.
So yes I say you should talk to her parents about this. I don't know if they'd listen but give it a try.

You should tell her parents what she has told you and that's all! They will come up with the rest of the conclusions on their own and they won't feel like your being threatening and don't tell them how to raise their daughter either they will be less likely to listen to you. Good luck!
