Teeth insecurity

So I have all my teeth I have and over bite and an interior cross bite aka my fangs are pushed back and look like they are missing. I am in the process of getting them fixed. I’m just insecure about it. I still laugh and smile but I always think about my teeth looking bad. Plus I’m going on a trip with a good looking guy next month...he’s seen my teeth because we’ve talked on FaceTime...and I’ve talked about them or whatever...any tips on how to feel more confident? I was thinking get my nails done and cover my smile in a cute way when I’m laughing etc lol...I know it sounds silly but this sucks y’all I’m 24 and my family couldn’t afford braces. But I’m working towards it on my own. I can give oral with them like his but it’s extra work to not hurt him lol I’m thinking I should get a mouth guard lbs. I’ve done a good job not scraping anyone but I just want me and his first embrace to be perfect!
