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”

just when I think i’m having a good weekend and I can forget about my struggles my brain tells me i’m not allowed to feel happy and that there’s always SOMETHING i need to be worrying about. so frustrating :(

Of course we can’t stop the inevitable but with my ocd it’s all I can think about. I’m afraid I’ll be alone for ever and I’ll fear forever. Fear does not stop death it stops life. But how do I stop fear??? I can’t think of anything scarier than the fact that our conscious will vanish for eternity. I am only 20 years old but I mean the last 5 years flew by like nothing.

I feel like im no longer living im only 17 and i use to be so excited to turn 18 recently i feel like life is pointless and its all i think about including philosophy and i never liked that before. It has taken complete joy out of my life anything simple like watching a movie feels pointless because it has no meaning and i feel as if my life has zero meaning because i am not important. I am constantly criticizing everything. For example i went to a concert ive been dying to see and when i got there i didnt enjoy it all because i felt like it was pointless. Is there anyone that has experienced this that has advice I feel like im in hell rn
