Anxiety On and Off

This Covid thing is getting into my nerves. At first I was okay with working from home setting and homeschooling but now I'm all burnt up. My head and my chest are pounding. I can't concentrate anymore. A lot of things are floating inside my head. I can't answer them all.
trigger: my mom in law wants to get back to home country (which was the original plan sans Covid crisis).. she basically takes care of my daughter and do some house chores. Aside from the fact that it will be just us again, I am worried if she will be allowed to enter home country.. quarantine and isolation rules.. and when can she come back here as the borders are not yet open to receive non-residents.
That's just the trigger, now I feel anxious with bouts of crying for thw past 3 days. I can't shake it off like those other time I felt anxious.
