Sucky birthday

Yesterday was my birthday. I turned 35, but it was nothing special. My sister took me to dinner, but other than that, it was just a normal day. My BF said Happy Birthday once and that was it. I got no cake, no song, no family... Nothing. I feel like I'm not that important to anyone. My BF said he would have loved to have done something but didn't know what to do. My sons stayed at a friend's house til 9 when they got dropped off at my place after their dads. They didn't even say Happy birthday when they saw me.

Does anyone else feel like they aren't important enough when birthdays and holidays pass and nobody acknowledged you?

I do everything for my family and my BF. And to get nothing, just makes me feel depressed. I know it's petty but it really does bother me.
