Endo help

I’ve been diagnosed with endometriosis for about 2 years now, I used to be on birth control but my insurance won’t cover it anymore and I’m currently working, every time I get my period, I dread going to work. I hate it. I’m in extreme pain and idk how to easy it. Pls I need advice and help. Like I’ve given up to the point where I wanna quit but I’m in too much pain.
