Tried adult protective services, about their treatment or mistreatment of you? (The way you mention freedom & control gets me concerned they, while trying for protective, may be overly controling or abusive... or controling and masking it as protective... or your relation is otherwise full of strife. Hard to say from a post.)
Or mentioning it to counselors at school if you attend one, any youth center or organization around, anonymous hotlines or warm lines, and the like? :)
Where ya living? As in country. Is there random jobs you can do and find a sliding scale therapist? Can you not work cos of disabilities or cos of the whole covid thing? Cos if it's the covid thing, there is still jobs going and it's worth looking.
we have more of a cheap health care thing than a free one, but a lot of stuff is free. i know you can get free therapy under certain conditions or circumstances (like under 18, poor, exc..) but I don't think it applies to me anyways
