I've no idea if I do understand, but will try....it sounds as though your not secure in yourself. I'm not saying this to judge you, but I think I relate (re others making you doubt yourself) you feel whatever you say may be met with disbelief, is this right? This leads to further doubt? Is this something you would consider talking about with someone, to help you gain clarity? In my own experience, I find that people will make their mind up about you, regardless of what you may tell them about yourself, I think it's common for us to experience, Hon. Hth
