Title explains it all. I hate my past self for being so immature. Especially in my tween/teen years. From when I was about 11 to when I was 15/16, I was extremely immature in some ways and it's embarrassing. I'm ashamed of the fact that I was that way when I was younger and I wish I could go back in time and fix all of the stupid things I did. I know I'm still young and I am more mature than I was back then and it makes me cringe thinking about all of the dumb things my friends and I said/did. I just really hate how immature I still was a few years ago. I hate myself in general.
