Can't sleep remembering this memory

Had a crush on a girl

Text her sent but ignored

Gets the courage and walks towards her
Without saying anything she starts showing her crush on her phone from another school

Walks away

.im average smart guy
.5.8
.maybe not that good looking but funny(tries)
What's the problem?maybe my shattered ego

(new here my friend said its a good way to post experience and let go)
