So I met this guys online, let's just call him JJ. We are always talking everyday, even in discord. The thing is, it would be great if I get him off my mind, I don't like catching feelings, I tried ignoring him but, I seem to can not. What should I do guys?

Mhh, first thing: Wouldn't you like to date him? You should perhaps reconsider the "don't catch feelings"-thing, what do you think?

If you seriously don't want a relationship, then I think that just stopping talking to him should be fine.
You need to get again used to the "not-having-him-in-your-life" and you have to be patient bc that's not easy.
But if there's a possibility about him liking you as well.. then think about it.
Love isn't so bad.

>>2 I agree with Kaster, unless you really don't want a relationship for whatever reason, that's fine, but it's okay to let yourself be vulnerable and fall in love. If what you're scared of is the online/long distance relationship, I can tell you that there's nothing to be scared about. I met my boyfriend online out of pure randomness and we've been together for almost 6 years and soon to move in together and get married. It's been great and I'm very happy I took that chance of being in a long distance relationship.
