Baby fever

Hi everyone,
 My husband and I have been ttc for over a year now. 
Literally.... Everyone around me is getting pregnant. It's like it's in the water or something. I am trying to be happy for everyone and humble but I can't help feeling envious.  Sometimes
I get down or I delete my social media apps. I can't help but think, when's my turn? Has anyone else had a similar situation?
What do you do to better it and keep your hopes up?
