“when I was asked what I wanted at the store the next time it was shopping time and said I don’t know…healthy food if possible…thats bad behavior….but I don’t know why and had to leave her room when I said I didn’t know what she was saying when I was told I had done something wrong…”
This example shows your mother reacting defensively, taking “healthy food if possible” as a criticism even though you have no idea why she is doing that – you only know it’s evidently “bad” as far as she is concerned, and you are accepting this like a truth you just understand. When you try to explain that, she just escalates.
You are not the source of your problems. It’s your parents, and probably their parents before them, and so on, who have a lot of unresolved issues which have not been getting attention since long before you were born.
Parents who behave like that are almost certainly not going to improve (without major intervention).
My advice is to think about what you will need to do before you will be able to move out of that house. Will they send you away to college, or can you get a job that will let you move out and be on your own? Try to focus on a plan for that, and meanwhile know that your parents are disturbed and you can’t fix that. You probably just need to keep avoiding conflicts with them as best you can, but try to understand that their behavior is not an appropriate response to you. I think you need to get away from them and try to find more emotionally healthy people to be around, and people who can help you work through such issues – good supportive therapists.
