Having a bad day

Lynn
I caved and took a test this morning...bfn 
Big white blank space staring back at me. I've been exhausted the last couple of days so I thought "yeah maybe this is my month". 
To top it off a friend called today and announced she pregnant with her second. It was an oops! She doesn't know about my issues but she just kept going on and on about how they thought about another and then she decided to test. BFP! Probably two months along...Same thing happened with her first. I'm so happy for her but as soon as we hung up I burst into tears. I feel terrible for being so resentful but I just can't help it. 
Anyone else ever react the same way to friends or family pregnancy announcements?
