I wont live past 30

My dad passed at 29.
Ever since I found out, I haven't been able to shake a feeling that I won't make it past 30 either. It's silly to think about and foolish to say out loud, like why wouldn't I live past 30? it wasn't like it was a genetic thing that killed him. Then those thoughts send you down a rabbit hole of other ones like "Well he did have heart problems, just like grandma. What if we have heart problems". It's stupid really but anytime I think about my future I can't picture myself past 25 and I don't know why. I don't know why I think that because he died young, I will too maybe its just fate.

Maybe I'm not meant to live long and maybe he wasn't either.
