I recently reconnected with my friends again and goddamn I feel and dread this coming on

Idk what tf it is but I get random boosts in confidence (I guess?) and my whole composure is not notch for like maybe a few days and then I lose that energy. No idea if that means I'm normally just not that way or if I'm not aware enough to understand if I should be doing something to make it so that I'm always like that. It's just so weird.
