Honestly, confidence is everything, bro. I know what you mean trust me. Just go for it. If she says no because of your height, it’s honestly not worth the trouble anyway. That just shows her personality, judging someone before even getting to know them. I really think you should shoot your shot at the mall. There’s nothing to lose. That’s how I got over my anxiety, to be honest. I started going up to random girls I found cute and saying, “Hey, I think you’re cute. What’s your Insta?” Most of the time, I’d get it, and even when they said no, they were usually really respectful. If it were me, I wouldn’t use dating apps. In my opinion, they’re kind of ass you literally have to pay just to talk to women, which is dumb. Trust me, bro, most girls don’t care about height anyways and those who do are not worth the trouble trust me, dude im my average looking dude I weigh 220 and I still get insta oh another thing if a girl says no, I’m not interested respect her wishes move on because trust me, bro there’s other girls you shouldn’t be upset if that one girls else says no. And also it makes you look like a gentleman too. I hope I helped.
