I'm sorry things are going so badly for you. I just want you to know that someone understands.
I am 29 and was diagnosed with bipolar disorder in 2000. I'm on meds and have a therapist and a great support system, plus I'm in a 12-step program, but I still have days when I feel terrible. I've been through several really bad episodes, and the best thing I can tell you is that it does get better.
The first thing I would do in your situation is contact the county or city mental health board. They can help you with anything you could possibly need--finding a new job, applying for benefits such as SSI (Supplemental Security Income) or SSDI (Social Security Disability Insurance), getting low-cost or free mental health care and meds, finding a support group. Also, see if your county or city has a chapter of NAMI (National Alliance for the Mentally Ill). I've done volunteer work for NAMI, so I can attest to the fact that they are an excellent organization.
Another thing that may help you is to contact the psychiatry department at the nearest hospitals and see if they are doing any clinical trials for people with bipolar disorder. You can get free meds that way and they reimburse you for travel and time that you spend at the hospital, plus you may even get a small stipend.
Next, it might be a good idea to contact Alcoholics Anonymous. Many people with mental illness do become addicted to alcohol and other drugs. Obviously I'm not a mental health professional and can't make a diagnosis, but it sounds to me like you're using alcohol in an unhealthy way.
Hang in there! It will get better. As they say in 12-step programs, keep coming back. Let us know how you're doing.
