How do I love someone and what does love feel like

Hey yall,

I am 19yr nonbinary (mab) and I have never had feelings for anyone, at least I don't think I have.

I am never been in a relationship, nor have I really talked to anyone with the intentions of trying to get in a relationship with them. The only time I think I had liked someone was in 8th grade, and that didn't end so well. I have tried dating apps like Tinder and to be honest I am a pussy. There was one girl that did have interest with me although I chickened out, ghosted her and then delete the app. 

I want to have someone to love but I Just don't know how, and to be honest I'm scared. I look around and see people in relationships everywhere, all my friends are in relationships or have been in one. I just feel left out, and behind. I'm scared to talk to people.

How do I love someone? how do I love people? What does love feel like?
