Giving up--tmi to

I've only been ttcing since January but I have pcos to. I'm on cd 117 and think I've reached my end. I've Had enough of the emotions, constant diahorrea from metformin, obsessing over cramps, peeing on 90 ovulation sticks and about 30 pregnancy tests. I can't handle it anymore. I want to tell Dh that's it's over no more. I just can't handle this waiting anymore :(. I know others have been trying for years! Where did you find your strength and what keeps your going?
