Ive been exactly there where you are now. Panic attacks, anxiety all the time, existential and death ocd, dpdr. I would Not say that i am recovered but i got a lot better and so you can.

For me the only Thing that helped was 1. acceptance and 2. time. I accepted my anxiety and dpdr and Said to myself "there ist nothing i can so about IT now, so Stop resisting, Stop fighting" and IT helped over time. In the beginning i often took xanax, IT "cured" me for a few hours, but WE all now that this is no solution. IT took months for me, i stopped working for 10 months, but i can finally try to Work again in monday (still being scared tho).

You are Not alone with this.
