I am sorry you are in this situation and sad.

Self-care and your wellbeing is first. Please don't let work be first in your life. It gets power over us when it becomes too important.

I don't know your situation, but is there a way you can look at your work in a different way? Reframe it a little. For example, look at it as a temporary situation that you will learn from as much as you can and a place to make money--not a place you are stuck at and can't take anymore. Feeling stuck is a tough emotion to handle every day.
