I'm very much an introvert and spend most of my days alone in my ivory tower, but I do enjoy the occasional human contact, very selectively. I always prepare myself mentally and physically for social gatherings, doing self care and avoiding any unnecessary human contact the previous day, and the day(s) after I need to recharge my batteries the same way. Humans are cool and all, but I have a pretty low tolerance even for the best of them.
I have a theory about having too much fun and then feeling very down after. I think when you are having a lot of fun for an extended period of time, more than a couple hours for me, the brain uses up all the possible dopamine, endorphin, oxytocin and serotonin it has, and has no feel-goods left for a while. I think my happy chemical reserves are low to begin with, or I end up using all of it without knowing how to spare some for the next day.
I feel seriously hungover after yesterday without having a hangover from alcohol, I only had two glasses of wine during the whole evening. I feel tired even after 8 hours of sleep, I am hangry and dehydrated, very irritable and moody as hell. Do not call me today, I won't be picking up. Of course this is all worth it because I had a lot of fun and I always know this is going to happen so I can prepare accordingly.
Ps. I just took this picture above, and it's a great contrast for yesterday's happy happy sunny day in Tampere with my fellow Steemians.
