It is an on and off conflict, but now its reach new heights. Normally I would ignore her which has worked so far, but even a minor question has her raising her voice before she explode into a one-side argument. Does anyone else deal or now how to deal with individuals like this? Its a stressful and tiring ordeal for me. I just want this to stop. Also, "she" is my older half-sister and has a history of bad decisions, but an innate skill in manipulating people. How long has she been like this? For as long as I can remember.

Seems like my mom and I live with her.

I don't have any type of help to give you but only words: Hold on. I know how it is, I know how tired and stressed you are and how you feel trapped.

Do you live with her? Distance yourself; think about your own well-being first.

Thank you, I need to be above this nonsense.
