What are some hotlines in the US that help teens?

First think of what your parents would do if they lost you.......I have had several friends commit suicide and it's just not fair. Nothing in this world is worth your life no matter how bad things may seem. Call your mom from wherever she is and tell her she needs to come home immediately. You need to talk to her about getting help. Depression is a serious illness and you need someone personal to talk to and help you!
