Does anyone else get anxious before starting injections?

I am resuming fertility treatment this month after a long break (8 months) and will have my 4th IUI in 2 weeks. The first 3 were last fall using Clomid (ugh) and a trigger shot of Ovidrel. I had bad mood responses and insomnia with Clomid but no negative side effects w Ovidrel. This time around I'm doing super ovulation treatment w 8-12 days of Follistim and Ganirelix before the trigger shot. I'm reading through the side effects and it's making me sooooooo nervous even though I don't have any reasons to be scared. Anyone else feel like this?
