I'm so stressed I want to fake my own death
Why are you so stressed that you want to fake your own death?
If people think I'm dead, all of my responsibilities will disappear.
I think that there are better ways to deal with stress that you should try out. I do not think that faking your death will help to alleviate any of your stress.
I need to have a break from all of my stress somehow, this seems to be the best way.
You should talk to a professional if you feel overwhelmed and stressed. Faking your death will make your family very upset and it's not an appropriate wat to deal with your stress levels. Try to find more sustainable ways to deal with your stress.
