Try not to feel too down. I remember feeling like that. You will get more experience and feel you are making progress then something will make you question yourself again. I think that keeping yourself on your toes and questioning yourself is a good thing. You will be all right if you keep looking at the MI'S and keep asking questions. I still sometimes feel like a newbie after a rubbish day of setbacks and problems. Keep your chin up.
