Hey I sympathise with your height insecurity, I stopped growing at 18 and remain 5'5" (I was always the smallest in my class). But honestly, it has nothing to do with height, I swear some women like shorter guys and many don't really care about height. Your insecurity is within yourself, I say this with respect. Any woman who cares about height is probably insecure about themselves, it has nothing to do with you.

My advice is work out, build some muscle and get fit. But much more importantly, go to therapy, work on your inner self, read. Become a better version of yourself, learn to love yourself.

I've been working on myself for years now and often, I really love myself. My height insecurities are gone, it's such a relief. I'm very grateful. Good luck to you.
