its getting depressing

Been ttc for almost 5 months but its becoming depressing because everyone around me is getting pregnant without trying. I know im only 22 but we've wanted a family since highschool and now that we feel ready it just isnt happening. Hoping this month is the month but i dont know how to be happy and hopeful. From my cousin being pregnant and a year younger than me to my SO best friend who didnt even want a kid yet. Its just so fustrating. Sorry wanted to vent..
