I've gotten to where work wears me out so bad I can barely walk for a a full day after I work (I usually work every other day in a week) it makes me useless when I get home and house work needs to be done. even housework wears me out and I keep it clean enough that there usually isn't much to do. since I found out I was pregnant I have been planning to quit and I think it's about time I do that but I am absolutely dreading the lack of money. I know we can make it without it but we won't have any extra anymore and that will take some getting use to.
