Keeping busy is good, as long as it's to work through things rather than to avoid them. Keep in mind, avoiding dealing with things takes a lot of energy and can add to stress too. Writing is a good way of engaging with things and sometimes a "narrative approach" can be helpful in figuring out how we'd like things to go and what we need to do to achieve that.
It's more that I work towards things rather than anything else. I'm heavily involved in a few organizations/other things and there's always a goal to be had. It gets very time consuming just because it's extracurricular and in addition to homework, tests, etc. Most of what I write are meant to be lyrics at some point or another, and based around a moment or situation.
It has happened to me, not infrequently, that I don't know how I feel about a thing until I write about it. The clarification is more apparent with poetry than prose - because a poem has to take a stance, so I think it tends to draw out latent opinions and condense/finesse them - but I think it's always helpful to write about things. At minimum you can literally see your mind working through things on paper (or a screen). I used to journal a lot. I'm trying to pick it back up although I'm not great at it. I think it's good for one. I think it can be like meditation in ways.
