OCD and depression. Happed to me.

Sir I am betch student of 21 years old.After passing 12th I forgot what I have just read.So I started japa meditation.Before memorising my book content first I do japa meditation (in japa meditation I repeat one word like 'om' loudly with closed my eyes.)... But when I do japa meditation for 2 minutes, after it my short term memory was not working.I think that I was hypnotised ...I forget everything like who I am . What I was doing.My short term memory was not working completely working. Then I went to local  psychiatrist. I told him that dear sir my short term memory is not working...I am not able to remember normal fact like what is today's date.What is time..etc So he made diagnosis of OCD and depression... My question is that Is diagnosis of OCD is correct... If not then please make a diagnosis that which mental deasease happed to me.
