I actually went through a phase of that around my 9 month mark. I had a lot of injection anxiety when I switched from gel to injections, and I would budget for about an hour to get it done. It slowly decreased down to just 5 minutes for the whole process.
And then around the 9 month mark, I don't know what it was, it just started to take longer. The first jump was 5 minutes to 30 minutes. Then an hour. Then 4 hours. Then until the next day. It was ridiculous. I would literally sit in my room, holding the syringe the entire time. I'd bring it up, get it close to my leg, and put it right back down.
I considered getting my roommate to do my shot, as I had him learn how when I switched to injections. But he has really shakey hands, so it seemed like it would be an even worse idea. What I ended up doing was setting time limits. I started with movies - I could watch a 2 hour movie, and sometime in that window I had to do my shot. Then bumped it down to TV shows - I can watch a 45-minute episode, and sometime in that window I had to do my shot. Then shorter TV shows, then YouTube videos, then listening to songs.
Some kind of treat afterwards is a good idea too. Ice cream, food you like, a haircut. Something to incentivize getting it over with!
And it's funny, my YouTube video of choice when I was having shot troubles was always the Shia Labeouf video 😀
