About my condition of daydreaming

Today while daydreaming, I was like 'I'm done with all of this stupid thoughts! I have to get out of it at any cost". Then I googled about it and came to know about MD in which I'm going through for almost 2 years! Earlier, I consulted with a psychiatrist and he told that I have the OPD and OCD problem but couldn't give me proper treatment so I continued daydreaming. Now it became literally a barrier for me and I'm done with this. I cant focus on my present. cant finish my every tasks like self studying, homework and doing other productive things. An exam of mine is near at hand but I failing to concentrate on preparing myself for the exam. I'm getting  frustrated day by day. I often in an alternative world which time is not real or sometime about my future about which I don't even know that that going to be happened or something!  and often I take my self in a whole fake world what doesn't even exist.
