bipolar struggling single mother without meds

i am bipolar and have not been able to afford my meds since november.  I thought i was doing okay, but bad things keep happening.  My son is in rehab for addiction, my mother has had two heart attacks, and my daughter had a spine surgeyr for scoliosis and got staph in it and they had to do a second surgery and she had a picc line in for 3 months.  Im divorced from an abuser of 23 years.  Im do medical typing and only get paid when im typing.  When i had to take care of my daughter and help my mom, i lost so much and had to take the equity out of my house.  I do not have any health insurance as I am considered an independent contractor so I have to pay for self insurance and it doesnt cover any of my bioplar medications.  Just my paxil was 228.00 for 30 pills, and I cannot afford to buy it anymore. Im so depressed that Im sleeping and giving up.  IM losing my home and its for sale right now.  I cant afford to go back to the psychiatrist because the bipolar meds they prescribe for me are brand name and my insurance will not cover.  i cannot afford a better plan.  theres so much more, i am just so desparate to get back on my depression medications without being manic so i can care for my family and just keep dinner on the table.  Im 45 and its becoming too much.  Im in menopause and cannot afford the hormone treatment which is also contributing to my depression.  I have lost about 30 pounds from anorexia from the depression.  Its 5 pm here now and i havent eaten all day.  i really just wish someone could help me.  The drug plans that offer free drugs, they take up to 90 days, and they only give small supplies, and i dont even qualify.  My income is considered to be at the federal poverty level, but yet when i turn for assistance, they say i make too much.  what can i do?  im so tired.
