Starting to wonder what's wrong with me.

My husband and I having been trying for a year now to conceive we don't have any kids.  Took a test this morning bfn I'm so tired of seeing those. I had a miscarriage June 1st at 8w2d naturally no D&C. Doctor told me I'm fine and come back in January if I'm not pregnant by than.My cousin in law announced she's pregnant with a baby girl (same due date as what I would have had) my best friend is pregnant and keeps telling everyone this pregnancy was a shock because I was on the pill. Everyone tells you not to stress or just relax and have fun. It's so hard to do that when you want this so much for my husband and myself. How do you keep going without getting upset or mad that you can't have it to?
