Writing can be helpful, and I'm glad it helps you! It may sound dumb, but not too long ago, I was feeling really sh*tty and I wrote myself a letter like if I were writing to someone in need... and it was harder than I though! Sometime we are our worst enemy and a bit of love from ourselves can go a long way.
Yeah I get it and it's positive that you recognize that. Sometimes even just believing that things can get better is hard.
Stay strong, my friend *Biggest hug ever*!
