Feel trapped in/scared of eternity

Sorry if this isn’t well written, been panicking a lot, need advice from people in this sub

Hello everyone, I have been struggling a lot recently, having panic attacks and the whole bunch about the concept of eternity and existing forever and sort of being trapped in existence with no end. ( been having an extreme existential crisis I can’t seem to escape;have extreme existential ocd/apeirophobia)

I have found it impossible to find any happiness in my life just knowing that none of it really matters in this life due to the eternal nature of us and “god” (same thing but different).

For some reason I have lost all connection to the people I love in my life and have just been feeling like an alone husk in an infinite/eternal world which I have no escape from.

I’m trying to find some advice from the people in this sub since y’all seem to have it more figured out than me and I feel like I am missing something. I have been looking out in different sources to help me but feel like my worries haven’t been fully answered from what I have seen and am now hoping for some insight from the wonderful people here to try to help with my worries.
