I need help... and fast

So I am not writing this to scare anyone or for this to be a suicidal post however I need help. I was diagnosed with depression and I was but on prozac. I also see a social worker about 2-4 times a month, but I don’t feel like I am getting enough help. I have cut myself and thought about overdosing and I’m scared of myself. I starve myself until I’m in so much pain it’s unbearable. My moods change automatically.I feel like I need to be admitted to a mental hospital but I know if I asked my parents they would say “you don’t need to... your meds will start working soon enough”. Well I don’t know if I can last another week or hell... another day. I hope you guys can give me some suggestions on what I can do because i need help so badly.
