My little sister has major depression and just came home three days ago after having been staying in a mental facility for three and a half months. Ever since she's been home I am so stressed out and anxious I don't know what to do. The chain of events that lead to us hospitalizing her was so traumatizing and I am terrified that it will happen again, and I don't think I can do it all again. I do college online, my mom works from home, and my sister's homeschooled until the new year starts. All she does is cry and talk about how sad she is, and I understand that she can't help it, but my days are just spent obsessively watching over her and stressing about her.  I just want to leave home sometimes but I have no where else to go.  I want her to be okay but I know that will take some time. I'm so worried about her and my parents having to deal with it all that I can hardly function. I just want her to be okay and I want myself to stop feeling so anxious about everything. I don't know what to do.
