I don’t think it’s gonna work out :(

I can’t believe myself. I’ve gotten myself in another situation where I had myself convinced that I didn’t have feelings for this guy. We both liked each other and talked nonstop but our age got in the way. (I’m still in high school and he’s starting college in January, we’re just in different times of our lives) we had a conversation a couple days ago and it was just really awkward and I couldn’t tell if the feeling was mutual. He told me he’d be in Cali for the next few weeks and we couldn’t really talk. I’ve been feeling just completely sick over this whole situation and it’s making me so mad because I feel like I’m obsessing over something that I never really had. I don’t really wanna talk about it but I need to get it off my chest. It’s like I’m fine and I’ve got myself distracted but then I listen to a song or think about him and a feel weird. Like almost nauseous but not. It’s making me so angry I just wish I wasn’t so upset over this. I don’t know what to do but my gut is telling me that I just don’t need him.
