I can't deal with my mom anymore?

My mom is in college right now and she is stressed out about it so she is making everyone miserable. She complains and freaks out over everything. If someone is in the bathroom when she has to go she flips out, as if we know when she has to go so we purposley go. She just complains about everything and i dont think i can deal with it much longer. I cant talk to her because she wont listen to what anyone has to say. And my brothers are both autistic so that stresses everyone. Also she has been diagnosed with bipolar disorder which she isnt on medicine for. But she is on meds for depression. Please help, im only 15 so i cant leave any time soon.
