(((Purple))) I'm so sorry you are feeling this way. I'm not sure what type of work you do but I always find anxiety at work to be the worst.

Your lungs ARE working. Put your hand on your stomach, chest or over your nose. Breathe in slowly, then out slowly. You can feel the air. Sometimes it helps me to do something and say "if I couldn't breathe, I couldn't have just done that". Then look at what you did, and see you did do it.

Take a washroom (or breakfast if you can) break. Just sit for a fee minutes

I hope your day gets better, I'm thinking of you and tomorrow will be better

Oh on a side note, have you talked to a dr about your panic attacks? They seem to be really impacting your day and they might be able to give you something that can help that won't make you sleepy. But that's for another day. Just focus on today, one minute at a time
