Ttc is making me a terrible friend

Stacy
My husband and I have been ttc for 19mos, I would round up- but I just can't face the 2yr mark that is fast approaching. 
In addition to the general dumpster fire of emotions that struggling tc has made me into... I have become a very bad friend. Facebook pregnancy announcements don't make me just sad anymore, they make me angry. I find myself getting so annoyed with my pregnant friends and find myself avoiding spending time with them altogether. I love them, I am happy for them deep down- I am just struggling so hard with my own reality. 
Anyone have similar feelings or ways to work through this?
