My mom had a nervous breakdown?

okay i need help. my mom is freaking out ever since she devorced my dad. shes saying he doesnt pay the bills, that hes spoiled, and then she goes on about how grandma is losing her memory, and how messy the house is, and then out of no where, she started crying and had a nervous break down. she said that she loved my dad, but she told me before she devorced him that she hated him! now, all of a sudden, she loves him again? btw, she was high/drunk, and then she said she was going to kill herself. i couldnt handle it, so i went to my dad's house, and kris (my aunt), came over to see if shes ok. im frigging so stressed out. this happens every night with her. she always complains about all the crap going on, and its driving me insane!!!!!!! life isnt even that bad, but she gets drunk and overreacts. i hate it :( please help :(
