You have described a number of symptoms that are characteristic of psychosis including ideas of reference (e.g. incorrectly interpreting events as having a particular meaning for you), grandiosity, odd beliefs and magical thinking, paranoid ideation, and behaving in odd or eccentric ways.
Those symptoms have diminished, but a new set of symptoms have emerged. These include feeling emotionless and lacking motivation. This new set of symptoms may be indicative of depression, side effects of medication, an adjustment to a life event, or a health problem.
Given your earlier symptoms, a diagnosis of schizophrenia would need to be investigated. However, the symptoms of psychosis are now gone and thus a diagnosis of schizophrenia may not be appropriate.
My recommendation is to seek a psychiatric evaluation from a mental health professional. The evaluator will collect an extensive psychosocial history which can determine what, if any, diagnosis is appropriate. Please take care.
