If you get an opportunity, see a medical doctor or nurse. Tell them about your OCD diagnosis and list your other symptoms -- low energy, concentration and motivation problems, frequent crying, emptiness, anxiety, etc. A doctor first might want to rule out physical problems with similar symptoms (anemia, thyroid, etc.). A fair number of medical professionals will be sympathetic to the possibility you are suffering from a mood disorder beyond the normal teen stuff.

I wish you well, Ihani.
