Some days I sit at my desk about to cry

I'm just unhappy. The woman that sits next to me is nice enough but some days her voice goes right through me & she constantly lies just to be part of a conversation.

I feel like everyday at work I'm not good enough, like you did this but I need you to do even more & more & more.

I wake up in the night with headaches, clenching my jaw. I snap at my husband  because my nerves are on edge. I took two weeks off around Christmas & I just felt peaceful, no stress, I got lots of things done around the house & just relaxed.

I have to question is this job worth it? I have given it 14 years of my life as of tomorrow, I feel stuck, because they are understanding about my husbands illness & the benefits are cheap.

But what is the cost to me mentally & physically?
