I think about quitting almost daily. I keep reminding myself that when I started, quitting was not an option. It still isn't really, but I am constantly feeling something new pushing my limits somewhere.
I also quit my job for school. I worked 35+ hours/week last semester and there was just no way I could do it this semester. I have 3 kids in 3 different schools--one is in preschool (3 years old) so I am paying for that with loan money (like you!). I have taken out too much in loans already and paid too much for books to really just quit. I would be SO disappointed in myself if I just quit. They'll have to boot me out to get rid of me...or at least that's the way I try to feel about it.
I am stressed about money. Stressed about not spending enough time with the kids. Stressed about housework. And then there is school stuff--be here, be there, do this, do that, read this, write that, critical thinking, care plans
, and please be more precise!
