I need some tips.

My best friend needs help with frustration. She gets frustrated SO EASILY. It could be something as simple as blowing a bubble, and she starts to cry and get overwhelmed.

Like, today, she untied my shoe and took it off and decided to re lace it. Apparently, she was trying to straight lace my Converse, but she kept messing up. She couldn't get it, and started crying and laughing at the same time. IT WAS SO FUNNY.

But, still... IS THERE ANY WAY TO HELP HER? I promised to try and help her with that, but I'm not entirely sure how.

Got any tips or suggestions or something?
