There are definitely a lot of amazing ladies here, and collectively we can give you a lot of advice and support. Has your doctor done an ultrasound to check for cysts?
My husband and I have been trying to conceive since we were married in July of 2010. I was diagnosed in July of 2011 with PCOS and put on Metformin. I tried 8 rounds of Clomid. I didn't successfully ovulate until 150mg, but even then O (ovulation) was sporadic. I was then referred to an RE (infertility specialist) who prescribed Femara/Letrozole. This is my 5th round of 7.5mg, and I've ovulated consistently for all but the first month. Sometimes Femara works for people who are unresponsive to Clomid.
I have also had a HSG (to check your tubes), semen analysis for DH (dedicated, devoted, etc. husband), more blood work than I care to count, etc. If this and the next two rounds don't result in a BFP (big fat positive), then we'll move to IUI, IVF, etc.
As far as staying sane? There's no one answer. I like to keep super busy. It helps me to keep my mind off of TTC (trying to conceive). I find coming on here to vent helps, too. These are ladies who actually know how you're feeling, which you may or may not have in "real" life. I think it's important to have melt downs if you have to. Yell, scream, shout cry, etc. if it will make you feel better. Keeping it all bottled up seems to make me more anxious and stressed. A great doctor is also key in this process. They can make a world of difference. At one point, someone on another forum also suggested making plans for the end of each cycle. Have one date planned with your husband as a celebration for pregnancy. Have another plan if you don't get pregnant...something fun to do together, maybe something you wouldn't be able to do if you were pregnant.
Welcome to the community, and best of luck to you and DH. We're all only a post/question away. Feel free to vent and ask lots of questions. We'll all do our best to help.
