Advice on emailing an apology

I went through a period of psychosis recently and repeatedly emailed a famous mathematician. The thing is, because of my background (on paper I’m well credentialed) he took me seriously initially and we had a correspondence. But I started spiralling into my psychosis and sent him something like 5 - 10 unsolicited emails. None of them were inappropriate, they were all about consciousness or math education but I just kept going. After medical intervention I’m doing well now and want to send an apology email. However I’m worried about sending another email on top of the ones I already sent. Should I? Or should I just drop it?

Update: I’m mostly going to send the email after sleeping on it. Thanks for your input.

Update 2: I sent the email

Update 3: No response
