My family is rude and controlling when it comes to how I dress

My dad was saying it was not healthy for me to be so bundled up in the summer weather. He said he would change psychiatrists for me and psychologists because they were doing nothing for me when it came to this issue. Even if had to pay out of pocket this issue would be addressed. He said I needed to meet them ( parents halfway and moderate). I could have just worn a fleece instead of a woolen coat and scarf blah blah blah. My mom was worse. She threatened to have me institutionalized. She was so pissed off she said she wanted to knock my skull against the wall and break my teeth. She told I was dressed like a retard. She yelled at me all throughout the car ride to Middletown Rhode Island. She said it was a shame and a sickness. What were my therapists doing for me anyway? What did I even talk about in therapy? Did I ever bring up my overclothing as an issue and of course not I wouldn’t say it’s a problem to my therapist because I’m a coward. Oh my god when it comes to the way I dress my parents are control freaks and need anger management. I wanted to beat both of them up and teach them some manners but I restrained myself.
