I really need to know if this is something I should go to the er about. I haven't eatin in 4 days, I haven't been able to hold any fluids down for 2 days, I have the symptoms of severe dehydration and I took pills that I got from someone and thought they were Valium to settle me down, I think they are speed, some street drug, I drank a whole lot of alcohol in the past few days and I'm scared that my body is shutting down. I'm severely suffering from depression, what should I do?
