Losing my friendship with my crush

I guess she ghosted me all of the sudden so I sent one final text, telling her I had a crush on her and saying goodbye more importantly. I'm not depressed but I am a little heartbroken, it's almost a foreign to me, almost 21 years on this planet, and she was my second ever crush, and this one felt so special, but I knew it never would've happened, I knew she wouldn't feel the same way, but I was happy being her friend regardless. Goodbye, I hope life gets better for you
