Is anyone else on a mission to learn every language that doesn't use words for when you go non-verbal?

As the title suggests, I frequently shut down and can't find words so I usually write to my friend when this happens (I always have a pen and notepad with me) but sometimes I want to verbalise my thoughts without a paper trail and without using my voice I turn to other methods. So far I learnt: the bsl alphabet and a few words(thank you, sorry etc) ; about 90% of Morse code(don't know q,b,j,z or k) and am currently learning braille.

I just want to know if others also decided to do this and if there are any apps that people use that help them learn quicker if so as I obviously can't just use Duolingo or whatever.

(Hope this was cohesive, this is my first post on here so I was nervous throughout the entire time of writing this)

Edit: as the comment suggests what I meant in the title is a verbal shutdown, I couldn't remember the term and idk how to change the title
