Psychiatric Hospital

I am thinking about admitting myself to a hospital to get some help. I feel like I am slowly losing my sanity with work, family, and school. I started a graduate program last year and it has been the hardest thing that I have put myself through. I also suffer from depression, anxiety, PTSD, and bipolar disorder. I am on medication but nothing seems to be working right now. I have tried exercising and eating better. I have tried meditation and therapy. Do anyone have any other tips that I can use?
