My AAC app finally works again! It's a free app with a format that fits on my phone and I love them very much, even if it's kind of buggy during updates.
So it turns out most of what I needed to stop feeling like my life was collapsing and everything was too much was to go outside and to let myself stop talking for a few hours. Talking and masking my AuDHD traits go hand in hand so in retrospect it makes sense
