I'm sure you've experienced this too. Right?

I'm sad... C's my mom raised her voice at me. I was at fault though but I tried to encourage and tell myself to be happy for her scolding me. C's I believe it's someone you want the best for, you correct. But the words she said is making me doubt myself. And it's new year tomorrow and I can't start my new year, doubting or having low self esteem about myself. I wish I could take tests to know if what she said is really true, c's I really act that way, and it's not like it's in my joy to act that way. I'm also trying to be better and act better. I might be of age doesn't mean I should be perfect or have no childish behavior or do some stupid things.
