I think most of us go through this at one point or another. We all wear masks it’s a coping mechanism. It sounds to me like you are a people person, you are very observant and a great networker. The talented mr ripley- a great movie. I am much like you where I realized how easy it is to make people like you and to connect with them. It’s something I do without realizing it. I adapt to what they need me to be that I feel like I am never myself. I have the opposite problem because I know who I am. Instead of discovering who you are, maybe figure out what kind of person you WANT to be (accidentally spelt wang there for a second was really funny). You can be whoever you want to be and if you don’t like who are then become someone else. Instead of emulating others emulate an idea, or principle. I don’t know if this makes sense but I feel like by asking this question you are on the right path. Based on the actions of what you wrote and reaching out on this forum I can tell who you are and it’s something worth holding on to.
Hope that helps.

Ps sorry if someone pretty much said this. It’s late and I was skimming over replies because I’m tired 🙂
