Feeling empty

I’ve been crying since my shift last night. It’s the next day and I literally woke up still in tears. It’s my day off to enjoy, but this company and the DLs/corporate have pretty much taken sweat, blood and tears from me at this point. When I fix things that need change, there’s no acknowledgment. My store had major issues and failing cfr when I took it over changed all of it, our rolling 4 week for cfr is 98% our inventory results were really good. I’m not normally a person who needs constant praise, but to be constantly beat with everything you’re doing wrong, but no acknowledgment of the good, can wear on a person after a while. I know I need to quit, but until I find a job with comparable pay, I’m stuck. I’m usually the light bubbly person that keeps everyone positive, but I literally have been feeling depressed. Does anyone know anything about LOA, for mental health? Is it paid? At this point I think I really need to take one, but I can’t afford to not be paid.
