I'm sorry you are dealing with this. The pandemic has been hard for most people. I hope your doctor has some advice I get panic attacks with similar symptoms from time to time. It usually seems related to my stress level. Unfortunately, I haven't been able to find a way to stop one if I feel it coming on. I just have to let it run its course.
We have another thread in this section where we talk about how Covid is affecting us. There are participants from a lot of countries. Maybe you will want to check it out. It definitely helps me to vent sometimes and feel like I am not the only one dealing with these challenges.
