Does my boyfriend not care that much about me? Or am I overreacting?

Last night I had a really bad panic attack. I have bad anxiety to start out with, and it gets worse on my period (which I'm on right now). I had been on Facetime with my boyfriend and he noticed the change in emotion so I told him what was wrong. He just told me not to worry and then proceeded to fall in and out of sleep so we sat in silence for quite a while. I then told him I was hoping he'd try to help a little
more and he told me he didn't know what to do/say and just told me to take deep breaths. I started to get more upset because I felt like he didn't care and started to cry. We talked a bit and I just told him to go to bed and he did. I was hoping that he'd maybe text me this morning or something to check on me and see how I'm doing but he hasn't. I don't know if I'm overreacting or not because I am on my period and tend to overact when I am. Should I be a little upset with him? Or no? If he cared wouldn't he want to know how to help me? We're 18 and have known eachother for 3 years if it makes a difference.
