need help I have no idea what to write for my essay

the prompt was tell me about urself n I have to keep it under 550words. Ive been brainstorming and im so lost truly. some things about me I considered writing about: (Context im 17F) -2nd gen immigrant -the period of my life when I struggled with severe depression -being separated from my twin at birth and only meeting them once a year on our birthday -being adopted by a relative at birth -family conflict with the title claim of « mom » the person who birthed me or raised me. -small moments where I stood up for what was wrong and I often confronted people who would make messes for janitors and help clean up afterwards etc. I’m involved in social justice related clubs. -having my name constantly mispronounced as a kid and feeling disconnected to my name at so young this is all I could come up with really. I’m not sure if the topics are too heavy or not and I do plan on connecting it to my personal growth and the positives that resulted from those experiences.. or do I come up with a really specific incident itself that shaped me. in that sense I could talk about experiences with my parents and how they shaped my empathy and understanding of the world (referring to a specific incident itself)
