I got my heartbroken and decided to cut my hair.
That's a big change. Why did you do that?
My short hair is easier, but also I liked that it made me feel like I looked totally different.
Getting a haircut after a relationship ends is pretty common. It's normal to want to change your look when you feel sad. But hopefully you'll be able to move on from the heartbreak soon.
I meant to prove to myself that I can find someone better.
You can change whatever you want about your appearance. IF it makes you feel better and boosts your confidence after a breakup, it's really good to change your appearance so it matches your new feelings.
