Still not pregnant with baby #2

I originally got pregnant with my son 1st cycle. But now trying for our 2nd kid and it’s been 6 months. I swear everyone I’m close to is getting pregnant and I’m starting to get frustrated. I’m frustrated that my body isn’t working as quickly as it did the first time. I feel also guilty for being annoyed I’m not pregnant only after 6 months when other women have tried much longer than I have. Any tips to help lessen the feeling of disappointment every month?
