What Is This Blue Feeling That I Am Feeling Recently Called?

I just realized i feel something that i cant recognize what it is called.

I was using a sheet mask since my skin is in bad condition.
I've been put under so much stress to the point that my skin suffered too from it.

I was surprised because the waiting time for the mask is 40 minutes while in any other sheet mask usually only need to be in our face for 15 to 20 minutes.
So, i was thinking what should i do while waiting?
Then i remembered how i had so much stress lately.
Like writing in my personal journal and in blockchain is one of my way of healing myself, improve my mind, leveling up my consciousness, make a video and talk (or more like rambling) like this is one of that.

Just by talking like this in few minutes, i feel like there's some light weight lifted i. my heart and mind.
