Hey everyone! I've only quite recently been "diagnosed" with dyslexia at 31 years old. What a struggle my school and working life was up until then.
I used to get angry with my not being able to write down fast enough (and without mistakes) what I was thinking and feeling however I have self taught some techniques which help.
So first one, I dont know about you but my brain thinks a lot faster than i write, so now i treat my hands like a student I'd teach and ask them to think about what they're doing 
seems to work, i think its having that control to slow down the thought process (also not to get annoyed if I go back and correct mistakes!).
Second one, learning emotional intelligence from videos online. No use from books right ). I found this to be helpful to control that frustration when things don't go right, be that with writing, people not understanding and them saying ignorant things or those days where up is doen left is right and gdhdvs is dhkdhdhd
Third one, understanding dyslexia and realising that by no means am I stupid but actually the entire opposite. I had someone do an intelligence test on me and I came out well above average! What a boost that was!
I think once you have the right frame of mind it easier to accept and those physical tools like programmes that read to you, bots who point out your spelling etc are just bonuses.
I love that I'm different! And that my skills are there, they're just not where others want them to be
