I think I have a cold and I’m really scared

I posted something earlier about going to a concert and being proud that I didn’t wear a mask. I’m afraid to catch norovirus and people keep saying it’s going around Like crazy atm and I’m like super anxious that I will get it. I read something that said you usually develop symptoms 24-48 hours after exposure ( it’s been 72hrs since the concert) but I so scared that I will get it and I’m like so anxious and I regret not wearing a mask. It’s like I’m so anxious I can’t sleep😩

I think I have somatic ocd I'm not sure but it's 1:27 and I can't go to a doctor or make an appointment. I'm getting scared of choking. I forgot a week ago how to swallow and lost the instinct. I barely eat in the day, but I try to eat normal food as an exposure. I know I won't choke but my body doesn't. I had a panick attack after eating like 7 spoons of rice and meat. It was all good until I started feeling again my throat very thick and like if there's a grain of rice. It really annoys me and my breathing is accelerated, I started feeling derealization. I need someone to calm me down. I won't go to work tomorrow, I'm so sleepy but feel like I won't breathe because of my panick attack. I'm alone right now

Here I am once again. I found a small moveable lump under my chin so I ended up going to the ER because i couldn’t wait to get in to a ENT. The Dr just felt it and said it’s a gland. I told her it doesn’t feel like the one on the other side. She did a CBC and said she isn’t worried about it. I can’t get it out of my head that she’s wrong. I have been looking at a Prayer request that went out from a well known radio host and read all the comments of people asking for Prayers due to them or loved ones having cancer. All I want to do is sleep, as soon as I wake up I get the surge of anxiety and panic. I fear death and worry IF there is no afterlife and this makes things 💯 worse. I’m tired
