I called to tell my managers that I've decided I wasn't coming back to work. It's been eating away at me for a few months on how frustrating and stressful that place is. I talked to my manager David and he seemed upset. He was asking if my decision is final and even mentioned me working part time if I wanted. Why did they never mention this until now?! Now I'm torn honestly and I hate feeling this way. I hate letting my employers down, and most importantly, letting my family down. Going to talk to him tomorrow, I think. I just want to clear the air and see where this takes me.

How is it so difficult to leave a job, even when it sucks so bad?? 😂😂
