I wrote journals for years, they help a little. I used them to vent, to discuss with myself about stuff I couldn’t discuss with someone else, put thoughts in order, practice calligraphy (people now praise my handwriting), etc. I never took it as a chore, so when I didn’t feel like it I didn’t write.
I went to cognitive behavioural therapy and that not only helped the most, it gave me tools to get out of the hole when I fall into it.
Also helped to stop pretending anything on a screen is social interaction. I ditched every social platform except reddit and now lemmy, these two, because I don’t know anyone feel different
It will give you an excuse to sit down and do absolutely nothing for 20 minutes for free.
Just try and see for yourself, it’s not some sort of investment so important that you need to do some research first.
