Relationship issue, need help?

My girlfriend has been very depressed lately and right now my only form of communication with her is through the internet. When she gets like this- let me rephrase this- every time we communicate we end up sharing her bad feelings her bad sorrows and I empathize, but being as suicadal as she is empathy is not what she is looking for. She believes she needs love but I wonder if she is ready for it she still talks about her ex with me.She won't accept that the whole world realizes she still has feelings for her she just won't admit it (we are both females by the way) If i say love to her she will get sexual in a snap which is not exactly what I wan't infact it seems our whole relationship has been based on sex and now that I am so far away-She doesn't understand that I just want to get to know her right now and I thought the space would help but I suppose it didn't. So I have been ignoring her on skype but she keeps e-mailing me-Basically she is driving me kind of nutts but I do not want to let her go because I know she will kill herself. To imagine I once thought I was a suicidal. I want to help her but my mental health is not much better than hers and I have started cutting myself again which I promised way the **** to many peope I wouldn't- E-mail me at theonlylyxzi@aol.com with a subject title pertaining to this if you can help please. Or answer below. I have communication issues just to let you know I have trouble saying what is in my head. You would not think it right now but-She wants me to be her doctor and refuses to see anyone. I have been told I am a genious but to me the only thing I have ever thought I was good at was english and according to the god damned spell checker i have seven misspelled... make that eight misspelled must be spelled wrong maybe it was one is..I don't recall. anyway I want to help her i want to stop her i love her but not in the way she "loves" me. I just don't want to see her gone. OKAY I THINK IVE GOT THE POINT ACROSS lolz skims over compain much... now i see the errors. :) Nine and so many grammatical.. and I am an editor...
