I very much agree with what Kyle said.
Please consider focusing on improving your mental health as priority, because your wellbeing matters, and you deserve to live a flourishing and joyful life.
I also agree that IQ is not particularly important in certain jobs, and there is something impactful for everyone if you enjoy it and your heart is in the right place.
Good luck :)
Sorry it didn't work out, but congrats on getting all those meetings and thank you for trying! :)
