Nobody here is going to teach you how to build a website from scratch. Go to a place like wix or weebly or squarespace and start playing around. I think both wix and weebly have completely free sites whereas squarespace just has a free trial.
The internet is full of tutorials on all of this stuff. Dive in and get to learning. If you struggle to put it together through patchwork videos go somewhere like Udemy or Lynda and take some courses.
Also, why does being shunned make you need a website? Are you just wanting to write about your experience? You can do that on forums or Facebook groups or lots of things without a website.
