Good heavens, are you saying that NOW you want to "slut around and drink all day?"

Not what I would call good choices.
Ok, seriously ~ INSTEAD of wasting any MORE of your parents money, get OUT of school now, or switch majors NOW -- there is no point in working towards a career that you're going to hate! Who wants to work in a hated career??
Your parents will be disappointed, yes -- but if you switch majors, it won't be as bad as if you quit college altogether! I hope that's not what you wanted to do!

You NEED a college education these days, believe me!
How about talking to your school counselor too. Perhaps he/she can help about interpersonal relationships -- or drop in here at the Relationships & Communications Forum. Try either or both!
I wish you the very best, my friend. God bless and take care. Hugs, Lee
