I also tend the drink sometimes. Just to ease the edge a little bit, to numb myself, to shut down the thought. I don't do this often. There is alcoholism in my family and I know I could easily get into it, my mental blockade stops me. In my worst time I would drink until I passed out but it made me feel even worse, as pathetic as it gets, as well as realise how similar I was becoming to some people... And I stopped. I never wanted it, I hated them more than myself at the time, so I despised the thought of being like them.
Instead, at the most basic I focus on the present. Never look forward, not into the next hour, not into the next day. I survive minute by minute until it become easier to breathe.
I used to hide under my desk often when I was a child. I still do it sometime, although I'm tall so it's rarely comfortable. Hiding under covers or make a fort helps as well. It feels safer when you can touch walls around with your shoulders and the only way in is before your eyes, blocked.
But what helps me the most is meditation and journaling. Sometimes poetry or drawing. Sometimes pacing around the room for hours at a time. Or rocking.
The most important thing is to keep your hands busy in some way, so that they aren't tempted to hurt you or to grab a glass, or a snack, or to break something.
Just keep breathing. Sometimes it's the only thing you can do.
