This might sound weird, please answer?

Okay so I'm getting my braces off in the next few weeks-yay!!! Well I literally just spent the last 45 minutes brushing my teeth. This sounds really stupid but I'm so anxious to get my braces off that I brush at least 10 times a day, for around 20 minutes each time. I don't brush my gums, so they won't get infected, and I floss 3 tines a day. I was thinking that the reason I'm doing this is because I'm excited to get my braces off, and also because I'm probably going to have my first kiss soon.:D well is this normal? Why would do I do this? And will it hurt my teeth?? Thanks <3
