Ok I am not going to take the time to read all of the replies....but I am confident that many people have made implications to Bi-Polar Disorder.
I will simply chuckle and say, while what you described "May" and I use that loosely; be a symptom of Bi-Polar disorder, if this is an isolated incident in your life and is not an established pattern of behavior, then I would chuck that right out the window.
Our society just loves to pin labels on people,...just like they do their clothing,...and often prematurely rush to judgement. I apologize for the utter foolishness that seems to run rampant in our society like an unleashed pack of rabid hounds.
I will suggest some simple things that may sound overly simplistic, but alot of times they are things that may be common place to us and get overlooked.
Are you pregnant?
Have you had any test run on your hormones to be sure there are not levels that are out of balance?
Have you recently changed birth control or changed, started or stopped any medications?
If so then the obvious thing to do would be to investigate further into which ever applies.
And last but not least.... Maybe you just need someone to listen to you. Alot of times EVEN PEOPLE WITHOUT personality disorders, emotional handicaps, and learning disabilities reach the end of their rope and I think people tend to forget that. It seems like the world wants to lable anyone that admits to having difficulties coping as someone mentally ill. In essesnce it is like the world is telling us that we should be ashamed for not handling whatever life throws at us with grace. For this reason, many people who truely do have a mental illness fail to get help for it because they are embarassed by what people are going to think. Truth is people have already formed an opinion about you whether you seek help or not. Usually people with the biggest opinions yet offer no real help to a situation rarely matter in the grand scheme of things anyways.
Admitting that poop stinks and life is hard sometimes is not a weakness, it is admirable and honest. We all need help and someone to lend and ear from time to time. Todays society as a whole tends to be very self obsessed and neglects the cries of others for companionship. We have let our problems become so big that it is impossible to see the importance of anyone elses problems. This is turn causes us to not be able to position ourselves to be a solution to a problem on any level. Perhaps you have not had anyone around in your life for a while that truly listened and expressed any genuine concern for how you felt or what you thought. This over long periods of time can harden our hearts and cause us to impulsively strike out at the people we love as a protection mechanism.
This post has gotten way deep and way long but if you ever want someone to just hear you out, I can always offer at least that...and offer it unbegrudgingly.
I hope by the time you read this that you are already feeling better.
Have a great Holiday!
