question: I have been extremely moody recently. iI have a history of deprssion and now its come back but only in certain moods, in a few cases i have been suicidal. Sometimes i go into hysterics for no reason where i cry or scream or because someone brought it on my ether upsetting me or getting me angry, while other times i get so angry i feel as if i could do anything and not regret it. Is this just normal teenage stuff (im a teenage girl by the way) or is it something else? just wondering.
