How to get over someone that does even like you ?

No confident, no self esteem, no friends, none of that crap. SERIOUSLY ? I hated when I search up a good way to get over a crush, or a relationship, this pop up:

I mean..Im not trying to bash on anyone. I know different method work with different people, BUT HEY, to be honest, its easy to say "oh I can just avoid him" or "I can walk with confident, and he's just one person", but when i actually try it for real, OH DARN ITS HARD >_<.
Even worst, I don't have much of any friend either to share the problem with. But guess what ? Im not friendless -__-.

 ONE WAY THAT I FOUND EFFECTIVE FOR ME IS...
  Don't avoid the guy, just walk pass him, say hi to him if he said hi to you. Avoiding him will cause a bigger damage do to you keep on thinking about him, wondering if he still like you, or maybe imagine that he'll still have some feeling with his reaction when he sees you . Just let faith decide what'll happen, sure it might hurt you, but TRUST ME, the more you see him, the more realize how you REALLY feel about him. And if you actually LOVE him, then well, lets god do the rest. Whats meant to be is meant to be. Overall, all Im trying to say is FACE HIM, DO NOT TRY TO AVOID HIM. IF he doesnt like you, you'll see how he react to you everyday and evetually get used to that feeling.
