I am so sorry you are suffering panic attacks.I suffered with them for years on and off.My heart goes out to you.All I can offer is that you give up caffeine (if you haven’t already).Drink plenty of water.Try to keep a regular bedtime.Try to distract yourself…like reading a book.Initially I found this very hard because I couldn’t concentrate and re-read the same line over and over again…but I persevered and got engrossed in the story.It helped to take my mind of panic and anxiety. I of course pray as much as I can throughout my day for as many people as possible.I find praying for pthers helps me enormously. I try to eat plenty of fruit and vegetables and avoid preservatives in soda drinks and foods.
Breathing techniques help…I am sure you can google these.Breathing in through your nose hold your breath a few seconds then slowly release the air through pursed lips as if blowing through a straw. Lavender oil is good to put a few drops in a bath or on your clothing to help you relax too.
God bless you
Memorare (Prayer to Our Lady)
Remember, O most gracious Virgin Mary, that never was it known that anyone who fled to your protection, implored your help, or sought your intercession, was left unaided.
Inspired by this confidence, I fly unto you, O Virgin of virgins, my Mother. To you do I come, before you I stand, sinful and sorrowful. O Mother of the Word Incarnate, despise not my petitions, but in your mercy, hear and answer me. Amen
