My first SC injection

 
I gave my first subcutaneour injection today!! It was only an insulin injection, but still.
Here they don't give insulin in a already loaded injection pen  into the stomach as we do it back home, but you have to load it directly from a virel into the syringe, and then they give it in the arm.
Everything went fine until I was going to insert it, and I started to shake!! And I could see EVERYONE was watching and pointing out that I was shivering, as that would have made my shaking stop or what?! But afterwards it was fine, and I believe some small tension is needed. As long as you don't show it. But wtf... people who know me knows that I have difficulties in hiding feelings if they really are present!!
 
What to do...
