Where is the light

Dear boss,

I give up. I freaking give up. I really don't know how much longer I can continue like this anymore. I cannot believe that I feel miserable when I am on leave. I thought taking a day off would help matters. Instead, I don't feel any better. I don't know what it will take to feel better anymore. I actually broke down today. I feel that I have gone beyond the deformation point. I am disillusioned and I am freaking tired.

Thank you for your patience and coaching me. Unfortunately I don't think I can contribute anymore. There is no way I can be a helpdesk and still prepare for the future plans.

Thank you once again.

Yours sincerely,
