Who am I?

It's wierd because I have no clue who I am, like people are saying that this is all part of growing up or being a teenager but like what even is this. They expect me to make all these decisions about my future, when I literally have no clue what to do with my life. I wanna like find myself, and just know who I am. Because emotions are just so strong all the time, when you're sad you're so sad, when you're angry you're so angry and just ect. Like what is this whole being a teenager thing because it's a big pile of (insert word here that I don't want to type). These are supposed to be the best days of my life but we're having all these horrible firsts in such emotion at the same time - falling in love, getting heartbroken, not getting over it, getting over it, making new friends and all this other junk. It's so hard, like so flipping hard - and then we have social media with all these amazing stunning people on who just make you feel so inferior and then ugh, it's just like why do we have go through this, why can't they make it easy for us. How do I freaking find myself, bc I'm done with this who teenager and not knowing thing.
