I'm very sorry, but your family dynamic doesn't sound very healthy at all. Not being able to buy clothing you like because they might not approve of it sounds very unhealthy.

You are out on your own in a dorm, this is your chance to find out who you are and what you believe in.

Your father is so far off base discouraging your friendships that it is disturbing. I could understand if your family found out that they did drugs or something, but I get the feeling that you are bringing good people home to them, and your family is still rejecting them.

These are your friends, not your family's friends. You are an adult now, and allowed to make your own decisions and your own friends.

You really need to consider therapy, because there are some very unhealthy dynamics going on here.

Best wishes.
