I'm sorry you are having to "fight" for support at home. grrr. Please go slowly with more changes in your life. Unless you fear for your life, maybe staying home for the time being is ok?

It sounds like, imo, that your dad had high hopes for you, perhaps unrealistic ones, ones that come from inside him and his own hopes...perhaps ones that were his own and were dashed at some point? I'm not sure anything you say or do will/can change him, but it's worth a try, isn't it?

It also sounds to me like he isn't very understanding of emotional/mental issues. Maybe by repeating some of what your T has told you, on how to cope, and add how this isn't a permanent situation, but that you'd like his understanding and emotional support, you might find a soft spot in him? IDK.

Your dad seems to be acting out and attacking you rather juvenilely, imo. Try to not respond to him in like manner, but treat him as an adult, and the father he is. People can learn to mirror what they are given...

Sit down with him with a plan... short or long term. and ask him that now this is where you are at, what are his suggestions?

Sigh. Raising parents can be so trying! TC
