We can't change other people or make them like us.
We can only work on ourselves.
It's unfortunate that you have to live in an environment where you feel you aren't getting the understanding or support you need for your mental health issues.
Do you see a therapist?
Perhaps they can help you find other living arrangements?
If not, perhaps they can involve the family in your treatment program so they will be a little more understanding and helpful?
Sincerely,
Pfrog!
