I've been thinking about it for years now. A couple of people have suggested it might be a good idea. I don't know. I've gotten good enough at keeping myself busy enough to avoid the thoughts and things that have made me consider it. I'd have a hard time articulating my problems outside of the occasional alienation of myself from...myself and blocking out the things I don't want to deal with. I've started writing more recently though, so maybe that's helping. Personal things are vulnerable though and I've never been comfortable with that.
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.
