I don’t understand (?)

Amber

So I’m 19 and I’ve never been in a relationship. I’ve “talked” to people and casually saw them but whenever they would try to get close to me I would instantly push them away because of my anxiety and commitment issues (#relatable am I right ladies 😂) anyway I love the idea of love and romance and I want to be in a relationship with someone but I physically and mentally won’t let someone in. I know I have to work on that but it got me thinking about my sexuality - I identify as Bi - and more specifically thinking about the idea I might be ace or aro yet neither of those things clicked. It makes me upset to think that I’m the root of my problems since this is so ingrained in my subconscious and I have no idea where to start to get better. Anyway, I guess what I’m asking is that is this normal? At least to a point? I know I’m only 19 and I’m still really young but I’ve never even had my real first kiss, let alone a typical “high school relationship” you know? Since I’ve never had a partner I can’t conceive the idea of what being in a relationship is like. I mean, I know what relationships are but I don’t KNOW how relationships are. Does anyone have any advice? This has been on my mind a lot lately and I don’t like it.
