As someone who has high-functioning anxiety, I have bad days, good days, and so-so days. I've always struggled to explain my so-so days, but this is the best description I can come up with:
Imagine you're in a glass tank filled with water.
The water almost completely fills the tank but has just enough space at the top for you to keep your nose above the water. For a while, you are able to keep treading water and breathe with ease, but you know in the back of your mind that if you make one wrong move, you'll be completely underwater. Now, I know that's not the most comforting feeling, but at least it's manageable. So you keep treading water but eventually, your muscles can't take it anymore. You have to let yourself go underwater for a minute to give yourself a break. You eventually go back to treading water... but with shaken faith. You know you can handle it for a little bit longer but not knowing how long you'll be stuck in the tank fills you with dread...
You just have to keep going, one minute at a time.
A quote from Moosa Rahat says, "Just remember even your worst days only have 24 hours." In the middle of an anxiety attack this might not seem so comforting, but when you think about it, 24 hours isn't that long. If you feel like the water is starting to drag you under, try to remind yourself that you're going to be okay. Go outside and lay in the sun! Doodle on some scratch paper! Binge watch your favorite Netflix series! Drink a Diet Coke and snack on some salt and vinegar chips! Do whatever you need to do to stay afloat! I know you can do it.
Always remember that you are so much stronger than you know, and you WILL get through even your most anxious moments.
