:/ Smiling makes me anxious

Ok so honestly ever since I was young I've always felt very insecure of my smile, especially before I got my braces. I have always been made fun of for my gap, big eyes, braces, and glasses. I guess I'm like the cliche nerd from movies. Every time I go to post something on Instagram I ask like 10 people if it's good to post, especially if I'm smiling just because im scared of the negative comments. I can't wait to get my braces off.. I feel like I'll feel and look much prettier!
