I still don't really ever get classic 'panic attacks' but my main symptoms include stomach pain and/or a dropping feeling in the stomach, insomnia, heart palpitations plus general restlessness and inability to concentrate. This sounds super weird but I always know my anxiety is getting bad again when I start getting this urge to break/grind my bones to dust - I can't explain why it's that specifically but I guess it's just a kind of intrusive thought (that urge to just destroy yourself)?
Given the current world crisis, it's not surprising that it's having an impact on people's mental health. However, I would say that my anxiety is fairly under control right now which I'd put down my medication working - obviously it's not a solution for everyone but if you've noticed having similar symptoms in the past, it might be worth discussing medication with your GP. The reason I say that is because medication can take weeks to actually work but side effects can happen within days. Often it's a lot of trial and error io find what works for you (for example, I'm on my second medication and it took 3-4 months to get to my current dose) so I'd only recommend it if anxiety has been a persistent issue (at least, pre-pandemic), since anxiety is actually kind of a natural response right now.
I hope you're doing alright but obviously if you are concerned (especially with shortness of breath), definitely talk to your doctor if you can.
