Letrozole

I have 3 prescriptions of 5mg Letrozole and tons of provera. PCOS 4yrs TTC. I did 5 rounds Letrozole last yr. Along with Metformin for 2yrs. I took a mental break. Started some amazing supplements and taking better care of myself. I quit taking everything prescribed. Got a HSG done a month ago, tubes are open and uterus looks good. Some thick lining..assuming from irregular cycles. I have such a mental block when it comes to taking everything again. I want to but, then again I don't. Especially when looking at this world. As I'm typing this I definitely need to pray about it but, just looking for input on what you would do? The rollercoaster is a hard one to ride.
