I'm just an outsider looking in, and have no way of truly diagnosing you, however, having quirky habits such as making animal sounds is completely normal. People are unique in their own ways and you found yours by being cute . The passiveness and lack of proper decision-making could be either an inferiority complex if it's that extreme or you suffer from a habitual lack of expectations and motivation. If people have put you down over the years and told you that you couldn't do anything, you have to break out of that mentality. There is also another possibility that you were just like that since birth, and it is just the way you are, and there is nothing wrong with that either. But if you, and personally just YOU and no-one else, think that it is a problem, then there probably is.
