Me [17 M] led on my [16 F] for year into friend zone, feeling worthless

So I was led on my a friend who was flirting with me for over a year. Originally I didn't really have any feelings for her but then I decieded to give it a try becuase it seemed as though she liked me. So I hung out with her and did develop feelings over time for this person. We went to our school dance two weeks ago that I had assumed to be and presented as a date. It went well and the night was fun but I was ghosted for a couple days before she finally said she just wants to be friends and can't do cute couple things. I was told I was nice and funny but I have a hard time believing that as I am quite nerdy and it took me a long time to ask her to anything and I only did so because I was sure our feelings were mutual. I was told by one of her friends that she doesnt really know what shes doing and may have unintentionally led me on and is just awkward in these situations.

Maybe more of a rant but I really need someone to talk to as I am feeling down and really worthless.

Where do I go from here, remain friends or cut contact? Is it really just that shes not ready for a relationship or am I just a boring person?

TLDR: Led into friend zone for over a year
