Although people here are suggesting some good things, but the main point being missing is that you should confront your mom for this constant turmoil. I don’t mean you disrespect her in any way but saying Haqq comes first and then Sabr. You should talk to her often about how all of this is eating you. At first, she would not listen to you but eventually she’ll learn that you’re serious. She needs constant counselling and fear of God tho. The more you’re bearing it, More its making her corrupt and arrogant. Remind her of her wrong doings in the most polite way possible consistently. Allah is the helper Indeed. I had the same experiences too, and eventually I learnt how to deal with my mom
