the ass part caught me off guard 😭 But honestly it's ok hun, I would say something like "that's part of life" but I know how hard it can be to not know yourself. It's ok to feel bad over it, but just so you know it's not going to be for so long. Yes people change bla bla bla, but finding out about yourself is something harder then puberty. It's about learning of who you are "but aven I said about personality" a personality can tell who you are. But don't worry, as much as you hate it you don't need to describe your personality. Small things can do that for you, even if you hate it it's not something bad. If I'm being honest I myself don't know how I present to others, so you're not alone. It's ok REALLY REALLY OK, even if you hate it it's still ok. You will know how to describe yourself, to know how to say who you are in the future. It can be far or close, but really all you need to know is that your yourself, and no one can beet who you are even if you don't know how to describe yourself
