Hello, I don’t have friends, but how do I do them and what should be the things that I have to take into account for that relationship?

How should I feel about them? I didn’t have a boyfriend either and I’m afraid I’m confusing the feelings that correspond to a friendship with those you have when you like something, I can’t find the difference, what has the world established that differentiates it? … both are relationships that have love, so I can’t find the difference, what is it?
