As both Angel and pyro have said, feeding from yourself will do nothing. It simply will not help you out at all. You could consider it wrong, but it is more like pointless and a waste of time and effort. And not even actually feeding. But what makes you think you are a sang, first of all?
And secondly, welcome to Vampire Angels. As Angelika has said, please take a look at the rules, and FAQ's. And if you have any other questions, feel free to post them or PM me.
