Coping? What's that?!

Amber
Hi, Husband and I have been actively TTC for over a year now with no success. I'm struggling to deal with the monthly roller coaster. The envy and jealousy for others is destroying me. 
I have been pregnant a few times but all of my symptoms are exactly the same as just before a period.
 Every month I wait for the day it was supposed to start then wait one or two more days and take a test, but it will be negative and sometimes just an hour later I get it. Every time I try to talk to my friends they always say that it will happen when it happens, not to stress, etc and I hate it. None of them went through even the slightest amount than I am and all have babies of their own.
I'm starting to go crazy, and don't know how to cope anymore.
