Just took my first injection 15 minutes ago - so nervous!

Ok folks, I did it. Took my first shot about 15 minutes ago. Im a horrible health anxiety person - If I were going to have any kind of bad reaction to it, would it have happened already? Im sitting here focusing on every tickle, twinge or tick in my body and taking deep breaths to make sure i can breath.

I must sound like an idiot - but I figure this is the best place for reassurance :)

Thank you all,

Adam
