I have had this problem, well as long as I can remember. I have always felt this way. I don't know if have even ever felt what it's like to have high confidence. I realize that this is the root of many of my issues and its crucial to me that I fix it. I used mentally bash myself trying to find why until one I just got tired of it. I don't care why, I just want to know how to fix it. I'm talking genuine, real, core, lasting confidence and self esteem and not some temporary "high". How can I get my confidence/esteem higher?
