am i being too sensitive?

So its my birthday today and my mom decided to invite her friend over that she hasn't seen in a while. They're coming over to catch up and eat. I played it off cool but now that they're coming today I just feel like shit. my mom's like help us clean, do the dishes, mop the floor etc. Idk why I'm so sensitive about it I honestly just want to cry. I never really took birthdays that serious I would always just have a small thing with my family. But I felt like when it would come to mine I always got the worst birthday out of my siblings. Not to say it was bad. But my siblings always got gifts from everyone but for mine some would forget and I would just get a couple. I probably sound ungrateful but I judt wanted the same effort on mine. I hung out with my friends the other day, they threw me a birthday dinner. And at one point one of my friends was like "wait we aren't you're only friends right? Like you're gonna celebrate with other people too, right?" and i was like yeah i am. But tbh I don't really have many friends and when my mom said she's having people over it just threw me off a little. I think maybe that's why lol.
