Tough spot I know.
One thing to keep in mind.
While you are going to meetings and getting slammed with the message that YOU ARE NOT GOOD ENOUGH - YOU DONT DO ENOUGH - and you ARE BOGGED DOWN WITH RESPONSIBILITIES - it is so much harder to step back and see all the BS you are surrounded with.
Take the next step - is step down. Tell them whatever you think they will accept.
Depression and Anxiety always works!
You can also say that with your new job you just wont have the time and your service will go down to.
If they give you LIP about that say - Ok will you be willing to pay for my "Health Insurance" "Housing" or other expenses when I am short and when I grow older?
Take this opportunity before you WASTE more of you life doing NOTHING.
Take it from someone who wishes he had those years you still have back.
