What is one thing in your life you wish you could go back and change ?

I wish I could go back and voice my frustration or confusion at certain times. What I mean is that there were times in high school where I felt like I was just stupid and I had to constantly do stuff on my own because I’d be ridiculed asking for help. Then when I didn’t meet expectations because it ended up being too much work for me, I ended up taking it personally.
