Is it normal that i need coffee to be in a good mood?

Is it normal that I only seem to be in a good mood or feel motivated to do anything after drinking coffee? I just spent about three weeks off from work for the holidays and on most days I could barely even crawl out of bed before noon. The few days where I was actually productive was when I was able to stumble down to the local Starbucks and have a large coffee.

It also seems to affect my way of thinking as well. I suffer from clinical depression had have been medicated in the past but have since stopped. A lot of times I feel hopeless and lonely but after a large coffee I usually feel less so and much more optimistic. Very similar to when I was on that medication.

I know people drink coffee to shrug off lethargy in the morning, but is it normal for it to help with depression as well?
