Chronic pain, might be endometriois can anyone help?

I am 25 years old and have been suffering from chronic intense pain for the past year. It is all on my right side starting in my pelvic area, goin up to under my ribcage and my lower back on the right side. I'm also tired all the time, and its getting worse. I have vomiting, nausea, fatigue, fainting, trouble emptying my bladder all the way. I am at my ropes end. I can't handle it anymore. I don't know if this is endometriosis or not. I didn't get insurance until 2 months ago and after a year of telling me it was all in my head and I just wanted drugs. The first night I went to the ER with insurance they told me I have cysts that come back every month. I feel intense pressure and pain all the time and sometimes feel like something is punching me. There was a few times where I actually fell to the floor out of no where because it felt like I had been punched in the side. Can anyone tell me if they have experienced anything like this? Please write me back if you do, I can't see a gyno for 2 more months and I need to know if there is anything I can do to get me through until then. I don't know how much longer I can deal with this. :'(
