Chat issues (maybe I’m just overthinking??)

I’ve been texting my friends during quarantine and I have one friend that I talk to a lot, let’s call him John. We’ve been messaging each other everyday but I’m the one who almost always texts first. I saw this as me probably doing something wrong if I’m the one always the one texting first. My anxiety made this rly bad for me so I stopped messaging him for a day or two and on the second day he sent this reaction picture that was vaguely along the lines of “uh oh did I do something wrong why did you stop messaging me?” I know that he has pretty bad anxiety too so I felt pretty bad and continued to message him often. He seems interested in our conversations but my anxiety makes me think otherwise. I enjoy messaging him but should I still do it if I’m the one starting conversations??
