It's my brother's wife. She is younger than me. She just got married. And I really thought she was good. But now it seems like she is not. She is blackmailing and getting furious with my brother when he speaks with my mother. She even threatened to cut the wrist. I am really close with my parents. I am really protective of my mother. It could have been normal family rift. But the thing is, there is deeply unusual issue with my brother. I don't even want to call him my brother. I don't want my brother in my life. But anything that happens with him, happens with my mom and my family. I know marriage changes everything. But I really just want my mom and dad not to be worried more than usual. More than worrisome level. I wanna like scream at her and insult her and just hurt her. Punish her. Like emotionally. But I really am not like that. I have mental health issue for few years. My brother is the whole base point of my issue. I don't know what to do. On one hand, I wanna move on with my life. At the same time, I feel shitty knowing that my mother and father are getting worried. I have no role in this. i hate feeling helpless. I wanna forget that my brother doesn't exist. But being in this family, which is everything to me, just seems not to let him out of my life. I don't even know what I am saying. I want a solution which I don't think anyone would be able to come up with. Sorry. I don't know why I am apologizing.
