Oh god I’m the least confident person there is to be honest. I second guess most things in my life but there are times when I do feel strong. I think it’s more of a be it, do it kind of thing? I’m anxious at times when I have to socially interact (online and in real life) with new people mostly. I tend to just assume no one wants me around so I feel you completely. 

I’ve gone through times where I’m more secure in who I am so I don’t worry as much but it’s so hard. Like I see these other folks who make it look so easy and I get angry at them. Which this isn’t probably helping you at all, sorry. 

I think confidence, like a lot of things, is all in who you feel about you. If you don’t think you’re great then you’re just going to assume the rest of the world doesn’t either. So don’t let those doubts overshadow the love you might have for yourself and you might start to feel confident. If people don’t love you for who you are then there’s something wrong with them.
