it's okay to feel unmotivated sometimes. you don't have to be productive 24/7. as long as you have long-term plans, everything should turn out fine. try to accept yourself & the situation you're in, find a good way to relieve stress and change will come. definitely prioritize mental clarity above all.
also, try not to fret over having conversations with your coworkers. constantly talking isn't necessarily communicating :)
The best way to find "introversion" (is that even a word? :face_with_rolling_eyes:) is to get out of your confort zone and do stuff you aren't used to.
Well i am not the best person to say this, cuz I keep telling myself i will do it. I will engage in conversations with strangers, I will start going out more, I won't feel weirded out to go to the cinema alone, but it never happens.
Usually getting out of your confort zone is very tiring and demanding, so start to take baby steps when you approach this "out of confort" zone!
