I'm so sorry they get so bad, but if sitting in the corner of your room helps, I think that's great. Don't feel weird about doing stuff like that to help with anxiety, that is a totally normal, and healthy response to anxiety. Hang in there!

Thank You, That Means A Lot! I Just Don't Know What To Do When I Experience It..

Sometimes being in a small, safe space can really help with anxiety. For me, being enveloped in a tight hug helps, so something similar in nature may be going on with you. I always try to take deep breaths first, and then if that doesn't work (i know this is nerdy), but i love to cook/bake so I will recite a recipe to myself with each step and usually that tends to work. please feel free to shoot me a message if you want to talk about it more :-)

Yes and no. When I have one I end up, at the end of it, needing to go away to some place quiet. I, usually, go to my room and stay there for a while in a semi-shut down state(sometimes in a fully shut down state). It then takes me anywhere from a couple of days to longer to recover and get to the point where I can fully function again. It depends on the severity of the episode I had. There are times where I can't get away and that's when my automatic response kicks in. My automatic response: I either shut down completely and go away to a safe place within myself or I half way shut down and numb the rest. I don't realize that one of these two things has happened till much later on when I fully emerge.
Have you ever given serious thought to the fact that it might have something to do with your childhood? If you can't remember any particular incident that could relate to this than it might be linked to a suppressed memory.
