erm... I don't know if you are aware of this but, there is lot of info pointing out that using anti-depressants actually does lot of bad and not good in that it actually increases tendency for suicide? You are better of talking with someone about all this, it works better then these pills... talking to your family (parents, partner, siblings), maybe some close friends also... I don't know your situation and how bad you feel, but I hope you don't do what lot of others do... if you know what I mean... everything comes and goes, bad things also...
But I have a partner, we've been apart for months and says the same thing, its all in your head, so I tried working all day, but my boss take advantage of me, I was just his slave
Apart as in away from each other, other cities, or separated? Anyway, if its that bad, you really should look for another job, I know you can't live without income and I know most people are working as economic slaves, this is common all around the world, its just more obvious in more poor nations, but lot of people in wealthy ones don't feel much better... essence of life is almost gone... but keep a strong mind, its all you have working for you by the looks of it.
