Always messing everything up

Ive been a “klutz” my entire life.  I guess you could say that i was born that way. Its just so annoying how i mess everything up. It seems as if i can never do anything right and when i think im doing something right, it ends up being wrong. For example, today i was marching in a parade with my band. It went seemingly well, to me at least. The problem was that i couldnt stay in my horizontal line the entire time because the person in front of me was too far behind her horizontal line. So if i had gotten in line with my line i wouldve been on top of the person in front of me and i couldve hurt her which i  didnt want to do. I stayed in line for the most part, to the best of my ability and yet later i got chewed out by a fellow clarinetist who was in my line. I remember her exact words, “You really need to learn how to stay in line,” which was said with such an attitude. I tried explaining it to her, ya know? but she was insistent that it was my fault and blah blah blah. Its just so frustrating when nothing i do is ever “right” and i always mess things up for other people.  People suck.
