I (16) do random things by reflex whenever I remember something embarrassing. So every time I suddenly remember an embarrassing moment in my life, I raise my voice, shout, swear, do the finger, or jerk/raise my hands/arms aggressively by reflex (and It just happens immediately without giving me time to think what I just did) and only after I did it, I suddenly think about why tf did my body do it. Please help me.
