it's completely mental

and more than just a little manic-depressive. how after a bad shift or at the beginning of a stretch i hate my job, and how after a good/manageable shift or at the end of a stretch i am all happy-go-lucky. ridiculous. i need to get it together and stop despairing. God is so good to me no matter my circumstances and the appearance. i need to keep hoping and trying. Lord help me.
