Hey Mich991 forgot to add about the tired part. That's me too! It is very common to be tired when your stressed, anxious, and worried. Even though you are anxious and can't be still, it's just useless energy. You can be so tired and unable to sleep just because of the giddiness. Thats how it is for me anyways. Again, If it gets to bad, I take a klonopin and it calms me down enough to sleep or get something done.
