How do I stop this panic attack?

POSSIBLE TRIGGER WARNING

I binged ate so bad today. I ate 2 pieces of pizza and a lot of cheese from the kids pizza bc he doesn’t like it. A kids apple sauce pouch and a danimals yogurt smoothie. AND a medium blizzard. I haven’t eaten this much in one day day for the past 2 months and I’m really trying to not make myself throw up. I can’t stop panicking. How do I stop it?!
