I'm really sorry to hear you are experiencing panic attacks. It sounds like they are very debilitating and scary for you.
While they do not all work for everyone all of the time, it may be worth giving some of these strategies a chance (if you haven't already) to see if they help to reduce your distress: grounding techniques (Blue Knot has a great explanation here of grounding: https://www.blueknot.org.au/Survivors/Self-care/grounding, there are different ways to practise grounding), deep breathing exercises (focusing on SLOW, deep breaths to try to control your breathing can help decrease some of the symptoms of panic), muscle relaxation techniques (have a look at progressive muscle relaxation - there are some great YouTube clips too), and distraction techniques.
If you feel that the panic attacks are having a significant effect on your ability to function (and it sounds like they are), I would really encourage you to see your GP or talk to a medical professional that you trust to get some support and advice with what you are going through.
Please do not hesitate to reach out on the forums at any time. We are here to listen. Take care.
