Why can’t I just go back to not worrying over death like this never happened and I can be happy without suddenly thinking “what’s the point im gonna die someday”

Hey there. What about if you thought like this. What’s the point of worrying.. I’m gonna die someday anyways. I might as well do my best to accept that and enjoy every day I have.

I have something similar. But in my case the focus is not the Death, but I always think also what's the point at some point we die and that's it. Which takes me to a sort of depression
