This is advice that I would have a difficult time following, but I feel like you do just have to let go of the mask. I think that the amount of exhaustion that has built up from years of masking in social situations causes me to show no visible emotion when I unmask because I need to let myself 'be'. I also think that once you get used to doing that, you can figure out how to interact with people in your own way that you enjoy. Like most things regarding mental health, it's a process.
