I’ve been dealing with my sister’s shitty behavior, and with depression for as long as I can remember... nine years I think, and everything I try to make her bossiness and jerkiness has not worked, and therapy doesn’t work either. I can’t take pills, it’s just getting too hard to be happy, and I’m getting suicidal thoughts. I can’t have arguments with people, and they all walk over me. What do I do? I literally think I’m losing my sanity... please help me.
