How do you deal with your birthday when you don't want to celebrate?

I will say, it isn't that I don't want to celebrate. But my family is poor, so I understand why we can't celebrate the way we usually do. I was already having a pretty bad week and my dad let me know that we aren't doing anything for my birthday and it just kind of broke me.

The issue is that I don't want to do anything else. I don't want to pretend like my birthday is a fun time of year for me or do the thing where I pretend I am loving everything bc I know they are trying. I want to lock myself in a room until my birthday is over. My dad wants to make breakfast in the morning but I just don't want to go. I don't want to get out of bed just to go eat away from my house (not at like a restaurant. We would just be at my stepmoms house) and then be forced to stay there all day until I come back home. If I say "I don't want to do anything", it gets turned into a guilt tripping thing bc I should do it so other ppl can be nice to me.
