My doctor is a idiot? Any advice?

Hi! I have a problem, I am suicidal and when I went to the doctor for guidance, he did not care at all. Really, I am anorexic and bulimic (not serious, but still...) and I have been suicidal for 7 years now. Finally, my mom gave in and took me to the doctor. My appointment was at 1:30 pm and I arrived at the hospital at 1:00 pm. We were forced to wait until 4:00pm. The hospital was not even crowded! Finally, when I entered the doctor`s office, I first weighed myself. At 14, 5 ft. 7, I was 88 pounds. Then my mom explained my suicidal problems and hallucinations, and you know what the doctor said? He said, "It`s just stress from moving, it will pass, just relax and eat. Next!" Also, I had to get stupid tests such as a blood test, a heart beat moniter test, and x-rays. Now, my mom is brainwashed into thinking that it will all pass. Argh! Any advice? :( I really need help. I want to live a happy life, but it is very difficult without any adults that I can trust.
