Hello, StillIntending. After reading most of your posts, to say you are in a difficult predicament is an understatement.

Do you regularly exercise? Mindfulness meditation may be helpful (look online).

Is college in your future? If so, make sure the institution has mental health support.

What is the age of emancipation in your state? Once you are considered an adult, you may be able to get help from the social services in the county of your residence.

I am assuming without knowing you want professional help. You are a person of value. Be your best advocate. Find a way to get the help you need.

I wish you well.
