Help fast. After calling the emergency vet, i gave my 8-10 pound yorkie 1 mL of h202 to make him vomit?

We gave our 1 yr old yorkie 1 mL (by syringe) of hydrogen peroxide because he got into my vyvanse(adhd) medicine and 1 pill was busted and 1 was missing after counting. The busted pill was everywhere so it was obvious he didn't get much of that but we thought he swollowed another. His heart was beating fast so we assumed he did and gave him the h202. Then I found the other pill so we know at most he got 25% of one 30 mg pill. Now he's acting cracked out and extremely scared. Sitting up (away from us) with his eyes closed. He threw up 1 big time and once small after about 3 mins. His heart is beating hard but not that fast anymore and he won't let me near him. He put up a huge fight while I tried to induce him (gritting his teeth as hard as he could). So hopefully he just blames me for his stomach ache and puking and is ok but I'm way more than worried. also I carried him outside with our other dog who wanted to play. After snapping at the chiweenie, the yorkie sat by the screen door and bolted inside to be by himself.(he normally thinks being outside is like six flags =(. ) sorry for the length but I would really appreciate quick response
