How do i know if i should go back into a psychiatric hospital? i just don't know anymore about anything

PsychiatricTreatment: I understand your distress and confusion. Possibly, Hospital treatment did not help with your thought disorder, mood disorder or other conditions which had affected your relationships, work and personal life; or you did not like effect of medications. See a Psychiatrist for Diagnosis, your present functioning; and discuss need for Hospital or Day Treatment Center with Therapy and Medication

Depends: A voluntary admission to a psychiatric hospital may be indicated if you are experiencing suicidal thoughts or you are not able to function in your life. If you are ever on doubt you can always ask your psychiatrist or go to your local emergency room to be assessed. If you are in doubt it always ok to ask for help.
