It actually doesn't sound like schizophrenia to me, but I am not a doctor. A lot of symptoms like anhedonia, thought blocking, paranoia, and memory concerns exist in other illnesses as well, including bipolar and depression. Anxiety issues also manifest in multiple things and can carry their own diagnosis.

The best thing to do would be to see a psychiatrist. It is best to see a doctor when you have concerns that are effecting your life.
