Does anyone else worry that they’re shaving years off of their life because of all the stress and anxiety

TW: Philosophical, Worry Does anyone else start to feel anxious at the thought of “what if OCD becomes fake one day?” In other words, “what if OCD gets debunked in the future?” Not trying to scary one just curious

I’ve been perturbed for a couple of months now with incessant thoughts about aging and dying. I really am not sure what to do. This feels like other OCD themes, but also really different, because this time, what I’m afraid of is sure to happen. I will either die, or age and then die. It’s been so difficult to enjoy anything lately. I just want to pull a blanket over my head and wait until death comes. Has anyone else felt this way? I feel quite alone. I am trying to enjoy life, but I just remember that it will all be gone in a flash. Nothing really seems to help me feel better. The only escape I have is in my dreams where I can fantasize about never aging or dying. Or at least being able to rewind the clock to have more time.

I worry I will have mental health issues the rest of my life. Not sure I could live a life like that, Not really sure why I'm posting this, I guess does anyone else have the same thought?
