What are some ways I can celebrate my birthday when choosing to celebrate alone?

My birthday is coming up in a few weeks. Unfortunately I am one of those who makes birthdays a big thing- for a few reasons. They range from bad past memories of my bdays to in more recent years finally having the desire to be alive. Each year I struggle with ideas of what to host for my friends and I to celebrate. This year in conflicted and getting extremely overwhelmed. I'm getting to stressed trying to accommodate. My bf also isn't really helpful and doesn't understand how much birthdays symbolize for me.

Thus, I've decide to celebrate alone! No friends no bf just me 😬. I don't know how though. Luckily my birthday falls on a Saturday so I was thinking a solo dinner. Maybe wrapping up a few gifts to open post dinner?

Im looking to do something between afternoon and evening. I'm on the east coast so winter weather is not on my side.

but please share ideas!
