Cover art for I Don't Need lyrics by Cranberries, The

It seems to be about someone realizing how shallow, stupid, frustrating, unfulfilling and wasteful her social life is. She sees how her so-called friends act stupid and are always drinking too much and their judgmental attitude towards her. And she still feels stupid herself because in spite of these perceptions, she stiil feels somehow attracted to these people, therefore she says to herself "I don't need to see you". This part, "And maybe no work done today" is her regret and guilt for not making better use of her time and instead spending time with those people, being stupid and childish with them. Or maybe it means she's so sad today that she can't get any work done that day.
