I really need good advice about my insecurities? Pleaseee?

[Nathan]

That voice in your head, the nagging voice that tears away at any sense of self-confidence or security that you have, needs to be shut out. I think of mine as a separate entity, a persona I call Jeffrey. Jeffrey is the personification of doubt, and while he does often have my best interests at heart, his constant commentary often makes situations worse if acted upon. I know that I sound like I have dissociative identity disorder, but this is more metaphor than anything. Just try to take your Jeffrey's two cents with a heaping teaspoon of salt.
