very sorry that this is happening, my first thought is ... move out ... but i do not know how old you are, so that might not be an option, enless you have relatives you can stay with.

My second thought is to record it. most cell phones have a record option for voice notes, if not use the video function in your phones camera.

or get a cheap voice recorder, or even most old time tape players will record voice.

do it just so your dad and psychologist can hear it to see what is really going on, and i would absolutely have your psychologist step in, that is their job.

and the ideas about finding other activities to do, outside of the house are for sure good ideas, try to occupy yourself outside the home as often as you can.
