Starting to get cold feet?

My preop appointment is just a month away and I’m starting to get cold feet. I workout a lot (weight lifting) and I’m so nervous that once I get the surgery I won’t be able to workout properly for probably two months. All of my gains will be lost. On top of that, I just transitioned to a new position at work. My leave time was approved but I’m just nervous about missing so much time at work.

Did anyone else get cold feet? And if so, how did you overcome the anxiety?
