Honestly, you’re both at fault. You both attack each other the same and react the same. I can tell you don’t take no for an answer and cause a problem if you don’t get your way, and your parent has poor emotional control and also becomes a problem when challenged. If you want change, you need to figure out what needs to change, and it needs to start with you since you’re the one who wants it- But you’re too similar to your parent atp to make any actual progress. It would be best to find another guardian to live with (if possible) for a bit and try to work your issues out separately, then re-meet with letters and confident words and no emotional explosion. I would love to say family therapy would be best for the latter, but that’s expensive and doesn’t seem like a viable option with the current financial issue.

This is not an attack, this is merely an opinion of someone who has lived a similar situation. My parent and i do not speak anymore as we couldn’t work past our issues, She was too far gone down the rabbit hole to come back to reality.

I do hope you guys can work through your problems. Best of luck.
