Suddenly I was stuck with my thoughts and I would get panic attacks

I was diagnosed with anxiety at 10 years old and I had finally reached a point of calming it down. I had school and clubs as a distraction and it was all fine. Then when the pandemic happened suddenly I was stuck with my thoughts and I would get panic attacks about the smallest things like not submitting homework on time or the WiFi being slow. I hated myself for going back but I didn’t stop it and let it take over again.
