Hey sotired!
I totally understand where you are coming from! Some days I look at people and I wonder what they think about and it makes me want to cry because I feel so insane! One thing that has really helped me a lot is something I learned on this website from The Panic Program. (I have to mention that it is a free 12 week program and teaches Cognitive Behavior Therapy - I mention that to everyone because CBT is an extremely effective way of learning to deal with this, if not beating it all together.) Anyway, I learned that when you're feeling like that, to remind yourself that it is just anxiety and that you are in control. I know that's really hard to think of when your mind is racing a million miles an hour. But, keep telling yourself over and over, this is just anxiety, I am not insane, I am strong, I can do this and I am in control. It helps me. Sometimes I forget this and find myself racing again. It takes practice and patience. I hope that helps!
Hang in there!
