I've been thinking about making this thread for a while, I just never got around to actually doing it.
The idea behind it is to post things that make you happy, that make you laugh, that make you feel good at the time you're posting them.
Little cute gifs, pictures, videos, messages to yourself, talking about something good that happened that day and so on.
Whenever you're having a bad day, you can go back through this thread and look at the posts from yourself but also from other people and remind yourself that good things exist too and that not everything is bad just because you're feeling bad at the moment. Like a light at the end of your tunnel. A reminder of happiness.
