I also want to point out that the feeling of being sick/tired after your 'episode' is also very common. As I've been told by a doctor, this is due to your brain going in overdrive for a few days, and then crashing. Typically it results in a a deep depression.

It always starts out small like this though, and it's extremely common for a person after their first few episodes to still not believe they have Schizophrenia, so please don't trust yourself.

I should also be clear, we could be talking about Schizoaffective Disorder. Schizophrenia is sort of umbrella term. I find it's often used incorrectly. Lots of people who suffer still have prolonged periods of being completely normal and lucid, some even go into year long remissions. It's a complicated disease, and you've displayed the tell-tale first sign almost to a T.
