Is it normal that i don't know what i feels like to like like someone?

I'm a girl. For a long time now I've been getting involved with people just for the emotional attention they give me, I haven't had TRUE genuine feelings for someone in God knows how long... I don't get why? I know what it felt like, last time I felt that was in 7th grade. I'm a senior now. I've never been in a real relationship, I just talk to them to satisfy me emotionally (yes, daddy issues; SERIOUS daddy issues). I've also had depression since like, 5 years now? & still going. Hell, let alone I don't know what it feels like to be truly happy either... Only thing is I've battled both for so long that I don't see how that could get in the way; I mean it could... But AH lol.

I'm just scared that I might not feel it for a long time. I know eventually I will but right now it worries me. Plus it bothers me because what happens when I do get those feelings? I'm probably gonna be crazy out of my mind for who I'm with. I say who I'm with instead of "the guy" or "the girl". I don't have a label for my sexuality, I just consider myself to be spontaneous when it comes to that, just whoever I become attracted to in that moment.

Anyways! Hope this is enough information! Thanks!
