The most intense physical pain I ever felt was waking up after impacted wisdom tooth removal. One side of my face was appr. 3x the size of the other.
The second worse was last week; waking up from anaesthesia after having all 22 remaining teeth removed. It's slightly better now and I'd put it at 8,5/10.
The worst pain I've ever felt was mental though.
It started almost three decades ago when my father killed himself when I was a teen. To be honest, I never recovered. I'm a shell of a human being begging for release (death) daily while being too much of a coward to actually do it.
Oh, and after returning to work with 0 teeth, my coworkers now amuse themselves by making me say tongue breakers. I already knew they didn't like or respect me before all this, but this really drove a dagger into my heart because it was someone I never would have expected it from. I've been at this company for 10 years and in this team for 5 and I'm fighting a daily urge to follow in my father's footsteps.
He really had the right idea. I was pissed at him back then but I have more understanding and respect for his decision every single day.
That's fucking awful. I genuinely hope you find yourself surrounded with people who love and respect you. I know life can be utter shit, but I'm glad you're still here.
Perhaps you can get a gofundme for dentures or implants in the future? It'd improve your quality of life and is worth pursuing if you feel like it's something you have energy for.
