Wished I had the power to send your unconfident to the rubbish so you weren’t afraid of being you. And display your personality. This is the right and the most pleasant thing to do by any of us. A first need.
I have been also going through life in most of the cases, wearing masks to hide my true self, which I considered inadequacy, different, embarrassing.
I encourage you to go on therapy. In regards to it, you felt it was helping you, somehow?
P.S.: Don’t feel forced to do anything. Only when you see yourself ready. It’s only my personal view, I don’t want you to take a risk that can mean you giving a backwards.
