Welp I’m in trouble I guess?

I saw a post in this subreddit about the morons who can’t calculate a dose. Turns out I am one!! After watching videos about injecting triz all day, going through this sub, I finally felt ready to do my first dose. Even as I was getting the injection ready, I read this subreddit about the air bubbles. Wouldn’t you know it, I went ahead and accidentally did 25 units instead of 12. By accidentally I mean not reading the instructions on the bottle and thinking I knew what I was doing since my dose was 2.5 mg. For my first dose ever. So. Please reassure me I’m not about to die on the toilet? Anything I can do? PS edited for spelling
