Anyone else obsess death of a loved one

Recently a deceased tenant was found in apartment next door to my mine. This is an extremely distressing situation and I am unable to let go of replaying the images of a funeral service removing the body through the hallway to the elevator and the super foul odor. This has made my living situation unbearable. I am hoping the landlord may allow me to relocate to another property/unit but my lease is not over for 6 months. They covered one night at a hotel while they ozone the air and hired a cleaning crew. Nonetheless I am immensely obsessed the air is still hazardous and another tenant will be found next to me again! I am compulsively holding my breath, blowing air out my nostrils, keeping the window open then close, spraying air freshener, avoiding the frequency of passing through the shared hallway, not going in the elevator, repetitive looking at the shared wall and their door, not touching the shared wall. Obsessed haunted presence. Obsessed I will get sick and die breathing in the air of the decomposing body. Obsessed with death the fear of the unknowing, what if no one found me like the tenant (7 days), how I will die, when I will die, what happens after death, being buried alive or cremated alive! Fear it’s not in my control! Fear how others will die! When others die! Especially my dog!! Fear I won’t be able to cope when my dog dies!

I lost my brother almost a month ago. if feels like it was yesterday. my biggest worry is when i snap out of the denial stage of this grief , that i’m going to lose my mind. it’s a scary feeling and i don’t know what to do. i’m still in therapy and don’t plan on stopping either but i just worry. i’ve cried here and there but all ive done is keep myself busy and distracted from this. i have my moments - i just am in such disbelief.

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.
