Night is the worst for panic attacks...I think it's because there's less distractions. During the day I think I am comforted more. Night is when I have too much time to think. And it doesn't help that I have been having trouble sleeping. Bought some sleep aid pills, but they make me have restless leg syndrome so I can't even take those.
So when I feel my panic taking over, I remind myself that it is a panic attack. I have to distract myself from it. I do that by getting on the computer, playing games, drawing, coloring, or talking to a friend (usually through text). My husband is great at talking me down if they get too intense. If they get to where I want to go to the ER, I take an Ativan, remind myself it is going to take time to kick in, and proceed to try to distract myself.
Once it is over, and I have to say it's been at night recently, then I have to keep with my distraction until I am too tired to think anymore. And since my hubby has to sleep with the tv on, I make sure there is something I find funny on, that way I am falling asleep with comedy on the brain.
In time you will learn what helps you cope and distract. I strongly recommend seeing a doctor and a therapist if you aren't already.
