I have been where you are!! Cobra is unbeliveable--if you could afford it-you wouldn't need to work!!
I found that I could go to the local family planning heath clinic and I received my gyne visit free with free birth control pills (this was before depo). It was based on our income-which was really low at the time but when I started working again-they still had a much reduced cost. The doctors were residents but I always received good care. I believe there was also a general family medicine clinic. DON'T be too proud to go--your tax dollars help fund these clinics so they belong to you too!!
Also PA has the CHIPS program for children that helps cover health care for low income families--again--your tax dollars at work--check into it.
Hope this helped a little--hang in there-the sun will shine again

and rainbows will appear

. My thoughts are with you--
