should I be worried?

So my bf and I of 2 1/2 years go to different colleges, so I only see him on weekends. During the week when we aren't together, we text throughout the day (some days more than others) & ft at night. He ft me today after a good day. I've been really sick the past couple of days, & out of nowhere he tells me I should go to bed now. I asked him straight up if he didn't want to talk to me anymore & he said no, you should just get rest. I have anxiety, & I just started to become overwhelmed shortly after he said this (from hw) & tell him my hand is literally shaking & he tells me I should go to bed then & I'll feel better tomorrow. He told me that tomorrow he'll be less busy & we'll be able to talk more. He was trying to study for a quiz he has tomorrow & I feel like he was trying to get me out of his hair, since when I was saying goodnight & everything he was rushing it & seemed stressed. I just hope that it's just because of the quiz & nothing else. Just thinking about it just makes me more anxious.
