My favourite hobby? .... there are several of them.
I like to paint pictures, read books. Sometimes I write something (poems or prose).
Playing Video games, surfing on 7 Cups, listening to music and watching Youtube.

Reading and Writing are two of mine.
@TeaForLife
those are great ones Tea
Listening to music has to be my fave one, I also like to cook sometimes,sing and a few other things etc...
Mine would be doing art stuff (making cards, watercoloring, & sketching) and taking naps with my dog.
Playing Video games
Yeah, I also use video games as therapy. The thing is that I work 6/7 (12 hours per day)... online games help me to relax, even 1 session in Smite can bring me positive emotions for the whole day. However, sometimes I even spin free slots or read comics.
Window Shopping! Travelling! Listening to music, poetry, long walks
@Irene4852, writing poetry, reading poetry, or both?
@BridgetAileen writing 
or both also is fine
Sleeping
Observing Nature. 🌿
Taking pictures. It just helps with paying attention to your surroundings, which sometimes I really struggle with. And also it makes you seek the beauty in everything around you.
