Feeling worthless

I have a fertility clinic appointment coming up in a couple weeks. It has been 11 months trying with no success. I tried to relax as much as possible this month I didn't use opks just tracked cm and hoped that taking away that extra pressure would help and instead of going for a fertility check up I could go for an ultrasound. But tested negative today and af is due Sunday. Getting sick of people saying it'll happen when it happens. Or the pity from people that were trying at the same time and are already pregnant and some even had their babies. I just feel so worthless for not being able to do this. Just wish getting pregnant was easier.
