i know reassurance doesnt help with ocd, but please can someone tell me this wont be forever.

i cant do it. i wanna rip my brain out. every single second of every single day i suffer. im in a constant anxiety attack that turns to pure panic every single day. im not coping, and im not taking care of myself. i cant do this much longer, certainly not forever. i just want to be happy again, is this even achievable? what if my obsessions are on something inevitable (death, nonexistence)? will i ever stop thinking this way? am i just doomed to suffer forever until it eventually happens?
