I need some encouragement

I'm 26 years old .I've been trying to get pregnant for over a year.im on leteozole 2.5mg everyday for 6mths now. I HAVE PCOS.its a bitch!!!.I'm on my last day of my period and I'm just sitting wondering if we should even try anymore. It's so stressful trying to do everything right with taking my temp,watching what I eat ,exercising .Nothing has worked.not at all.i feel like I have dust bunnies instead of eggs. Anyone else ever feel this way?! Is it worth it to even try anymore?!?!?
