Knocked down

I had my neurologist appointment at ISIS today...I was tired and I don't think it went well. I'm scared of the outcome because I don't want my concussion symptoms to be dismissed. I think it was my fault how the appointment went though because I should have been more prepared knowing how bad my memory is.
Fingers crossed his report will be ok though, I have to wait a few weeks for it so in the meantime I must try not to worry about it.
Why do I usually find Dr's to be so scary-I need to get over this fear.
