I am notorious for feeling the existential tug in the month leading up to my birthday, so I feel you. Do something that you don't get to do that often that will make you happy, go to your favourite restaurant (or cook your favourite food), walk in your favourite place. Try not to be internal and indoors on this day, try to do something that celebrates even if it's in a small way.

After all, you were born x amount of years today and that's joyous. I won't say you're loved (by the people here) because when people say that to me, it comes across a bit hollow. But by virtue of you being the type of person who chooses to spend their time in leftist spaces, I sincerely hope you find a way to have a joyous, happy birthday. Maybe that is love.
