Fresh Out Of Hope

After battling PCOS for the last 10 years and TTC for 12 months, I found out today the cysts on my ovaries are now also in my uterus. Greatly reduces my chances of conceiving naturally and greatly increases my chances of having a miscarriage if I ever do conceive. I'm pretty much fresh out of hope now, having nothing left in the tank. It's just not fair. I don't know how to "stay positive" when all I want to do is sit and cry.
