Hey

Coloring books are pretty cool!
I used to do them a lot last year and have recently gotten back into them.
I only do them when I'm stressed and starting to over think cause while coloring I usually don't think about anything and when I stop I'm still stressed but a lot calmer, and as long as I'm calm I usually can handle stuff. So my motivation behind doing them is probably preventing panic and stuff
Originaly I got into them because of therapy. There we had to paint and stuff and since I realiced it actually helped I bought some coloring books since its easier than doing something from scratch (I'm not much of an artist).
So I'd say, try them! Thei re amazing!
