Looking for friends/motivators who understand

I am 21 yrs old and I was diagnosed with PCOS when I was about 15. I have all of the symptoms of PCOS and I do not have a period at all. I don't have health insurance at the moment so I can't get any help from a doctor. It is EXTREMELY hard for me to lose weight. This is my 6th day on MFP and I weigh weekly. Last week I only lost 0.4 pounds. I am extremely overweight, and I gain weight easier than anyone I know. :(

Height: 5'5"
SW: 269.4
CW: 269
GW: 150

Something I did not know until recently was that PCOS can cause Liver dysfunction. I have been having problems with my liver for 2-3 months. Liver problems also can cause weight gain. Also a weeks ago I was in the ER and was told I have gallstones. :(

I HAVE to lose this weight!
