All people need other people, need "help" and it is not uncommon for young people to feel the most need for help these days. You are on the cusp of a lot of great change, moving from childhood and being dependent on others to being on your own and having to run "the show" yourself.

What you study is what interests you. Many people study psychology and become psychologists to help themselves; we only live our own lives, if you think about it. In our wanting to help others, the "our wanting" is what is prominent. I would start out as a psychology major, take your basic courses, see if psychology really interests you (it's a lot of lame science to me, about how your sight/brain works :-) and also look into what counselling your school might offer. I started therapy when I was 20/the beginning of my junior year in college. There is no shame in being in therapy; if you decide to become a psychotherapist with a PsyD in psychology, you will have to have a year of therapy yourself, as part of your education. None of us are perfect/without difficulties in this life.
