how to stay sane during TTC?!

My husband and I have been trying for 3 years...6 mc later.. I've been diagnosed with endometriosis and PCOS. My doctors for lack or better terms suck...never offer any good options. I have crappy insurance so that's probably why. I'm so done with calculating probabilities of what ifs every day...so done with being sad and angry and so entirely exhausted with seeing other people be moms when they suck at it... help me stay sane. I don't want this to drive a wedge between me and my beautiful husband.
