What is my problem?

I'm working on Trellis in Swish Superwash. I think when I posted last I was four inches in on the sleeve. It's a couple days later and I'm maybe an inch further along. I keep messing it up! I've already done the whole repeat once correctly, but I've ripped the same two rows out three times now. THREE TIMES. I love this sweater. I really want to complete it. I'm never going to be able to do that if I can't get through rows 13 and 15 on the second repeat!

I'm going to clean the living room and try again. As soon as I finish the sleeve, I want to post a picture.

Deep breaths....
