Nothing that you've mentioned sounds like schizophrenia to me, except possibly the last part. It might just be a symptom specific to you.
I've had all the same symptoms at some point during my 6 year DP/DR journey and I'm still completely sane.
Actually, the problem is that we are too sane.
It's completely normal to ask existential questions and is kind of odd that other people don't.
It blows my mind to know that some people will never even think about existence, whereas someone like me has had obsessive existential thoughts since I was 10.
You know the drill.
Exercise, eat well, sleep well and distract yourself.
