Need your advice!

My husband and I have been TTC for 5 yrs now. This has been a very long struggle for us both. I try my hardest to stay positive and not let it get me down. But we all know how easy that is... Right?! So I'm not sure how to handle my best friend being pregnant! I know this might sound silly but she can read me like an open book. I can't hide my disappoint from her. Any advice from you ladies and how I can deal with all these emotions and not lose my BFFFF!
