I agree with the other commenters that it's a big failure of the company if you can't take time off. That does need to be resolved immediately. It may not be your fault (for example, if your coworkers are being lazy or if you're not being granted enough support staff) but imo it's your responsibility to at least raise the alarm that the company would be sitting ducks if you got hit by a bus.
If you've documented everything as well as you can and you've notified the company of the risks of having everything fall to you, you've done all you can do.
I also want to just raise... it sounds like you have a set of feelings that you can't fully explain. You might consider talking to your EAP or doing some short-term therapy to figure out why you feel like you are obligated above and beyond the normal employer/employee agreement.
For further actions, you may consider blocking this person and/or reporting abuse
