Plus you gain weight. I feel like a trapped gerbil in my cubicle. I notice when I have time off from work I lose weight.
I feel bad for you, but I know the feeling. I'm retired now. But I recall that I couldn't wait to escape my cubicle and get out to a restaurant. I didn't particularly need to, but I enjoyed food to get my mind off work, and I hated my boss. He would chastise me, telling me I should eat my lunch at my desk so I could be available and work at the same time. I felt like decking him. Eating out was my escape from being around him.
