I just got a new fear

Okay, maybe not really 'new'. I mean it's about an older fear of mine, but I guess it changed a bit. I used to be very afraid of losing Dennis to someone else, that he'd find someone who's better, or maybe not better, but that he'd start loving someone else too, or that he'd just stop loving me. Now it has changed a bit: I'm afraid he will love the freedom he has right now so much, that he prefers to keep it, and that I will lose him to that freedom. I'm afraid that he won't contact me on Friday/Saturday/Sunday because he prefers to keep the life he has had since Monday, because he can do so much more then, and his parents, friends and colleagues might as well like him more.
Anyway, I'm just saying now that this was enough worrying for today. I just took a quick shower and jumped in my bed after that (well first I brushed my teeth 'n stuff), but as soon as I lay down, I got dizzy and it hasn't stopped yet. Or well, not fully: I get dizzy, then I feel okay for like 3 seconds, and then I'm back to being dizzy or feeling weird, and I also have an earache. Now I really remember how I felt for 3 days straight last year, it really sucked actually.
But well, I should just go to sleep and see what happens. I can't help but to worry to be honest, not only because that stupid fear of mine, but also because I have no idea how Dennis is doing, it really annoys me. But I guess he's doing fine, probably better than me now, at least. Otherwise he would have contacted me.
