Last semester, We were forced to take turns answering questions in Japanese. I got 90% of them right, but when I used a couple of incorrect particles, I got publicly corrected and I just wanted to dig myself into a hole and die. I don't like doing things wrong, and what's worse is I hate being wrong in front of others. At least in private I can fix the issue and go on. But after this, I felt so ashamed. And to make matters worse, my family bought me a fluffy exercise mat for yoga... I can't balance on it or anything, and I know my instructor won't like it, so I refused to take it to class. This upset them, but I don't know what else to do. Any way I can get over this issue of mine? Any tips?
