Hi Eric,
So sorry to hear your having these thoughts.
Talking to a therapist, or a counselor would be the best way to go. Talk to one of your parents and see if they can set you up for an appointment. Some therapists are on a slideing scale for fees, and some are even free (this takes some looking).
These thoughts that are making you depressed will disappear, or occur less frequently. Just be prepared to talk freely about everything that bothers you. They will do the rest.
Hope you feel better soon.
