Here are some helpful, actionable tips you can try the next time you need to calm down:
Breathe. ...
Admit that you're anxious or angry. ...
Challenge your thoughts. ...
Release the anxiety or anger. ...
Visualize yourself calm. ...
Think it through. ...
Listen to music. ...
Change your focus.
Now, you already did the second step, you admitted that you feel anxious. I know you're busy enough as it is but you have to take some time for yourself. Clean your room and if you don't know how to start, begin with the big stuff first like your bed. Then to your clothes, and then to small stuff like pens.
Think about what you'll do when you get to Florida (the beach, disney, crab legs!)
I've been to Florida for vacation, and you need one too.
I consider you get professional help, and I hope you have someone who is willing to help you clean.
Do your best!
