Should I seek therapy or find another option?

I am a functioning person who can do school work and got into a competitive college. I am 18 years old and about to go to college, but I have some problems. I never leave my house because I live in a weird location and can not drive, use the computer way too much, obsess over body image and food, have frequent crying spells, parents claim I go to them too much for help and that how upset I can get can be taking it out on them, and I have very few friends because I go to a school that is unaccepting of me and sometimes my sexual orientation. I know I can go to college and function, but I don't want to have an internet addiction although I am in my house too much because I never leave and it seems preventable, but I am worried about the future from some turmoil I had experienced. What do you think I should do?
