wet mouth trick
A dry mouth is a danger sign for your body. Drink something or swoosh some saliva around in your mouth.
Make sure to hold something warm. The easiest way is a nice, hot cup of water tea.
Pay attention to your breath and breathe deeply and slowly.
Say the opposite
Say the opposite of what you are thinking. Example: Turn “I can’t do this” into “I can do this.”
Don’t tell yourself “I’m anxious.” Say instead “I am experiencing anxiety right now”.
Know that nothing matters that much because everything is better than being dead.
