that sounds more like what happens w bpd (borderline personality disorder). i have that happen to me all the time where my mood changes from the one extreme to the other in an instant like i can go from sobbing to laughing just like that but yah id def look it up & see if u relate bc it feels a lot more manageable when u know theres a reason ur brain acts the way it does & why u feel the way u do. my dms r also open if u want to talk abt it at all!!
