Well, either this Doctor is an arsehole or he was attempting to do REBT (rational emotive behavioural therapy) on you, which is a harsher version of CBT. Basically it's a type of therapy that makes you really think, a do it or die approach. Of course there are many options inbetween living unhappily and death. I don't believe anyone lives their entire life unhappy, there will be pockets of joy here and there at the least.

I don't know, I could be completely off the mark, maybe someone got hold of his cell phone and just decided to be really mean.
