Just scared the living hell out of myself

Just scared the living hell out of myself

I can't believe I did this. My poor ds has a cough that's keeping him up so I got him some cold medicine and gave him his dose. When I left his room I had a funny feeling so u went back and rechecked the bottle. I gave him the wrong freaking dose!!!!! I gave him 10ml not 5. I freaked the hell out. I've never had to call the poison control before. My hands were shaking so bad I could barely hold the phone.
