Has anyone else felt like this? F18, M18

Okay hi 18F and my partner 18M have been together 2 years and for the past couple of weeks Ive been feeling so off. I just wanna preface by saying I’m sorry if this isn’t completely coherent I just needed a place to talk about it fully

We recently went to a party for one of his family members and I got food poisoning and I felt incredibly ill and anxious the whole time I was there at the time I thought nothing of it but even when I recovered the anxiety never left, anytime I look at my partner I feel incredibly anxious and guilty I’ve spoken to him about how I feel but I just don’t feel better

Just to preface my boyfriend is an amazing guy and he does Everything for me and he is the sweetest person I know so I don’t understand how I could be feeling these things

I constantly feel like I’m on edge and I constantly worry about our future together and if it’s going to work out, I recently got accepted to college and will be moving in with him and I feel like this might be the reason for why I feel this way, but I also sometimes feel like the little things he used to do aren’t there anymore, we don’t game together anymore or spend a lot of time together when We’re not physically together as we’re 4 hours apart and travel to see eachother,

a lot of people keep saying to me like family and friends that if I move for college there’s a high chance we won’t work out and it’s freaking me out

Little things like him posting me isn’t really that common anymore as when he has to take time off from work to do things with me he usually can’t say the truth of why he needs time off, hence he can’t post me unless his colleagues see and tell on him, some other things is he doesn’t watch the stuff I send him on instagram anymore just the small things I used to love that we did together

I know love is a continuous effort and you can’t stay in the honeymoon phase forever but I just miss those small things

Another thing I’d like to mention is any of these feelings I’ve expressed here I have communicated to him about and I just can’t seem to relax, I just want some outsider opinions without anyone knowing me really

so my question is has anyone else had these feelings? In longer relationships is it a phase that will pass?
