I experience quite bad anxiety, and when I lay down I notice I can hear thumping in my ears, it seems like my heartbeat? It is very slight but it is worrying me. I notice that my ears are sensitive to loud noises and sometimes when someone opens a door sharply it gives me a slight panic attack. Also when I chew it recently it seems much louder in my head. I can't explain it but please could someone help me as I think being anxious doesn't help
