Is it normal to have poor situational awareness after a long break?

[meatlover]

Feeling horrible after I did my sim check.

Did my TR 6 months ago, and by the time my skills test was due, I was way on top of the game and everything seemed easy.

After that I only did 14 flights as PNF, and not a single PF sector.
Did my sim check yesterday to remain current, and though it was easier than my initial skills test, it felt as though the work load was extremely high, I couldn't focus on many things at the same time, had to be prompted a bit, made a bunch of silly mistakes.
Feeling very low. Is it normal to be rusty and lose situational awareness with a long break?

Thanks in advance guys.
