No, it's real chess. Top players are actually quite good at it.
And, you may be slow and methodical and, perhaps should never play blitz. However, my experience is the more I play...I get faster. I suspect you will get a lot faster, too, in time.
For me, rapid chess at 10 minutes per side is as fast as I want to go, although I could play 5 minute games...but not my cup of tea. It's chess, alright.
Try playing slower games. I didn't even know what blitz was when I started out.
Definitely.
It has always been my opinion that blitz chess, et al. are not real chess. This may be due to my slow, methodical temperament however.
