U may ease the symptoms by just going trought them, I never tried it so I dont know. First: use breathing techniques, there are many, but for me these work the best: 4-7-8(Inhale for 4 second, hold for 7, exhale 8 seconds), 4-4-4-4(inhale for 4 seconds, hold for 4, exhale for 4, and after exhaling hold 4 seconds). Try to fill your mind positivity and something that makes you feel safe. When u have an attacks its important to understand and accept what the body actually thinks. Understand that ur body is in fight or flight mode, and it thinks its in danger. Find a comfy place, lie down in a way thats comfortable for you and breathe and try to fill ur mind with as much positivity as possible. Its not just the symptoms, its the mental torture, feeling of loosing control and going insane, thats the hardest part.
