bipolar is a change in motions e.g sad to happy then to mad. If someone notices a quick change in your emotions daily then you may be bipolar but not just that you also need to be evaluated at a therapy or hospital to see if you are truely bipolar.
you would know if you were because you'd go from being sad or happy one second then mad or angry the next. its a mixture of emotions in such a short amount of time youd feel a certain way for no reason at all
I have had bipolar for four years, and if they put you on medication do NOT take lithium it makes you gain weight. I'm on Latuda and it's is awesome. I used to take geodon but it made me sleep all the time good luck
