I agree with Jessica, I have no idea what is going on there. It is possible that mom does not understand the extent of your problem, or understands but cannot accept that your issues run as deep as they do. I know that suicidal ideation can be a form of addiction that needs help similar to that of drug or alcohol addiction recovery programs, and there are programs out there that work if you work on them. There are online chats available for GLBTQIA young people, and even a Skype meeting or two, and these all deal with suicide and SI/SH problems. Google the Trevor Project for a good site that helps GLB young people.
