How is your mental health holding up? I think you need to maintain perspective on what you can control vs what you can’t control and properly calibrate your expectations to something short of perfection. You have an extremely strong resume and will be a solid candidate at a variety of top schools. You cannot however control which schools will offer you a spot and you can’t achieve perfection nor would even perfection guarantee you a spot.
Slow down and breath, do things you are passionate about and seek out friends and fun. If you start to feel pressure or depression seek out help.
In addition avoid or ignore adults that are insensitive, accusatory or just mean.
I don’t see you as having “faux humility” but as a 17 year old trying to get reassurance having faced a mental health issue. Know that most adults will respond with compassion.
