I sometimes feel like my body is too slow, and that it can't keep up with all the anxiety that's inside me. I feel physically tired and somehow slow, slow movements, slow breathing, slow swallowing, slow heartbeat /and of course, I keep thinking that I will stop breathing and die, even though I know that it will not happen/, but at the same time I feel intelectually and emotionally tense and anxious. Does that make sense? It's hard to explain, but I was wondering if anybody else experiences a similar thing.
