First of all, examine your choices. You don’t have to work at a job you hate. That is, unless you hate everything, in which case you are definitely depressed, without question.
There’s so much work that needs to be done in this world. Surely there’s something you enjoy? Find that thing, and make a career around it.
Yeah, okay, you have to do some minimum maintenance for the body, including providing it with shelter, food, basic maintenance, etc. And that costs money, so of course you have to pay the bills. Is it really that bad to have to do that? (This is where I begin to suspect that it’s maybe more than just your un-optimum choice of employment that’s got you down: you may be depressed if this is all that you can see of life after you get out of the job you don’t like.)
If ‘clicking and typing at the computer’ is so boring, then find something else to do with your free time, too. I enjoy the hell out of clicking and typing at the computer—I try not to publicize this at work too much but… I enjoy doing database development work as a hobby at home, which I turn in at work and for which I’m paid more than I should be. (And that lets me fluther at work, which is a nice byproduct.)
Yeah, I think you suffer from some mild depression, and you should probably see about getting that handled. Maybe a vacation and a change of employment would help, but… I think you’re talking about some fundamental ‘self’ issues here.
