I don't particularly enjoy my job but I like my colleagues. I spend 10 hours a day with my colleagues so we have lots of time to chat and bond.
After work I always feel really happy and bubbly and energised. Yet after a few hours of being at home my mood plummets and on days off I can physically feel my mood plummeting to a depressed kind of state. My default state on my days off is to stay in my PJs moping around the house feeling really down and depressed although I do force myself to get out and do things.
I have always been shy and presumed I was an introvert. What do you think causes my mood to plummet so drastically?
