Need some advice on patience.

I really wanted to be pregnant this month, I took 2 tests Monday that were both negative and as if that wasn't bad enough I started Af yesterday and it's so freaking heavy!!! I feel depressed and sad and keep crying over little things. My best friend that I normally talk to about stuff like this had a miscarriage and got mad at me when I tried talking to her about it. I feel so alone. How am I supposed to be patient when all my friends have kids or are pregnant?? Please any advice is helpful. Going on month 4 ttc.
