Que:Did I have depression or OCD or both

Sir i went to Psychiatrist and told him that I have short-term memory loss.I think I am developing Alzheimer.I had negative thinking.I had no interest in enjoying thing like listening a joke, watching a television,or even playing a game on phone.Some time later I saw that I am not able to recall that what happened around me before 5 min.My episodic memory was becoming worst... So my psychiatrist first made diagnosis of depression so treatment was Fluvoxamine 50 1-0-1 and amoxapine 25 0-0-1.Within one  week I got recovered 30%.And now I was able to do daily tasks like bathing, watching television , playing game.But after one year of treatment I left this treatment because of my long term memory issues.my short term memory was ok now but I experience that my long term memory is not good Now second time my psychiatrist made diagnosis of OCD on prescription  and give me Fluvoxamine 50 1-0-1 and clomipramine 12.5 mg 0-0-1.Now I was feelings 10 time better than before.So what was my problem
