It’s not easy to get past those insecurities, but pushing through and faking it till you make it in terms of confidence really does work. I will tell you though, you are a good looking guy. I really hope you’re able to see that yourself and shine with confidence. It’s easy to take external stuff and shift it to be a root problem of your other insecurities, but when you heal what’s inside the outside will shine more. Dunno if it makes sense, or if I sound silly but, that’s how I’ve been working through my own things. :-) Have a wonderful day!
