About thirty minutes ago, me and my brother were having a fight (verbal) and I walked into the garage to find my mom trying to kill herself with car fumes. I opened the garage door and just stood there, lost of words. She said that next Monday when holiday break is over, and everyone's at school, she'll kill herself. I really think she's going to do it. She already tried a few weeks ago (her cat was the only thing that stopped her). I don't know what to do. Everything I say just gets bounced off... Any ideas about what I could do?
