What Do You Suggest For Depression?

I am bi polar have been since 1987 have been treated by about 3 doctors in the past 26 years The phychaiatirst I am with now and have been with for 15 years or so has me on carbamazepine 200 2 a day and citalopram hbr 20 mg 2 a day. I am bottomed out I have never been any worse than I have been the4 past few weeks. When I ask about a change he wants to up this medication I have been on this 3 years and nothing has ever worked this long at a time. I get immuned to it or something. I would like someone with a fresh look. I think we are in a rut. I have blue cross blue shield insurace and I also have a sleep problem I take colozapam, seroquel, tramadol, and tizandine a muscle relaxer at night it is for my back. the sleeping is going well, but during the day i could care less if I live or die, I work to keep from doing something to hurt myself I need someone quick to help me. I don;t like the ideal of going on the internet looking for a doctor to treat a mental illness, but i am kind of at loose ends. I work daily run my own business, and live a full live, but it is a very unhappy one right now and i do know what depression is i have been there way to many times help needed not talking or phschology been down that road for 20 years talked out just need right meds.
