anxiety/depression rating

Anxiety is about a 10 + going over the top of my head.  I think that is exaggerating.  If anxiety was a rating between 1 and 20 and 1 being not at all and 20 being the absolute worst.  The number would be 15 on the scale.  Ech why is it so high? oh selective mutism.  

Depression I would say is about an 8.  That's not good either.  Why?  

What does it mean when I feel like I have to throw up every time I leave the house or when I get out to go to the store? Or when I get up to the cashier and they ring it up and it's over $200 and I feel sick to my stomach.  I bet that is normal isn't it?  

Here is the thing. I have discovered that I have Asperger's and it is on the autism spectrum.  I think selective mutism and autism have the same symtoms just about.  Selective mutism a person is mute in some situations but not in other situations.  Okay, I'm having some issues here.   My issue is that I have difficulty describing things and explaining things.  Is it true that is part of Asperger's?
