Should I go to a mental hospital ?

I have a eating disorder , I self harm , I hallucinate , and I just dont feel happy anymore . I hallucinate by seeing dogs and a black outlined man with a deformed face telling me to follow them. When I look in the mirror I see my died friend sometimes . I hear babies and singing children when I am home alone . I cut and pull my hair out . I throw up sometimes and restrict food . I am 14 should I go?
