You could fight for legal emancipation but when a child does so they are usually expected to move out and be financially independent, not sure of your age.

Do you have other family you can move in with whether you file or not?

It’s wonderful that you have a Therapist to discuss all this with. I’m sure he or she can help you come up with coping strategies.

Religion is a very delicate situation to tip toe around. Is there any possibility that you can learn to just not let things affect you when it comes up? Kind of nod and move on to the next subject.

It sucks that your not getting support from your Mom that you would like and frankly deserve , but life often isn’t fair and we all need to pick our battles

Good luck , I hope things get easier.
