I started off feeling great. more social and active. i was sleeping less, more productive, working faster,cleaning, singing and dancing. now im feeling the worst feelings that ive ever felt in my life. this happrns every few months. im still sleeping less and am still more active. still getting things done faster. but instead of feeling good im vey irritable andeasily agitated. during these times i usually end up raging- throwing things and hitting people and screaming and crying. so far ive only thrown my phone because it was going so slow.ive had to literaly bite my tongue and walk away to cool off. i feel this anger inside and i just start crying. its during these times that my bf refers to me as incredible hulk. i dont know whats going on during thesr times. ive heard of mixed episodes but it was never explained to me. is that what this is?
