Man, if you want to become confident in your life. Just work a door to door job. You're not gonna care anymore. I see people all the time and try to start a conversation, sometimes it goes well but it also goes bad. And you don't really care anymore about rejection. In a day you can get hundreds of rejections. It helps you improve a lot and you never know who you might stumble into.
I can relate, the ex-bsf i had before she would spill everything I told to her to even the ones that I don't even know. She is just too fake like I can tell by her behaviour but I was friend w her for 10 yrs because I wasn't good at social at that time and making friends were like the most impossible thing for me. After we ended our friendship, I found true bsf who is fri w me for whom am I.
Another thing about touching your face a lot is that it causes you to look anxious/nervous, which can make you look very unattractive. I've tried studying the way that more attractive people move, and realized that I do a lot of things that aren't good. Face touching, looking around excessively/quickly, looking at the floor, staring at the walls, fidgiting, eratic movements, etc. One of the most interesting things I noted is that attractive people have more intentional movements. For example if your face is itchy, and you really must scratch it, then raise your hand smoothly and intentionally, scratch slowly and intentionally, and keep your hand there for longer than you think feels normal, then slowly and intentionally lower your hand when you're done. This can apply to lots of other things too. You need to show that you know what you're doing with your body, whatever you do.
