I was selfish.... do I apologize?

I am so angry with myself.

I have a cousin who is going through the toughest time of his life. I found out last night that he admitted himself into a psych ward because his depression got so bad. I found this news out via text last night from my mom when I was three margaritas deep out with the girls.

I woke up this morning, forgot about the text and went about my day. I typically send my aunt photos of my LO every few days because we live across the country and she loves the updates. This morning I sent her a photo of my LO and her response was empty... then it hit me. THE TEXT FROM MY MOM!! MY COUSIN!!!! Wtf!!! I am sooooooo mad at myself for not addressing my cousins condition and just selfishly sending her photos of my little one.

How do I salvage this? Do I text her about my cousin? Just let it go? I am not even sure if she knows that I know about my cousins condition. Ahhhhh! I feel like a shit bag.
