ok so , this will be very strange, you should try it if you want.
i have been studying the Psicomagia stuff by Jodorowsky.
its a therapy that combines, psicology, magic and theater acts.



so this is what you should do.

you suffer from anxiety and have shortness of breath

take a shirt and put it around your neck you will act a self-strangulation
5 self-strangulation of 10 seconds you will do.
after a self strangulation you will breath again and you will revaluate the experience of breathing, you have to thank that you can breath again, you will apreciate and you will do the self-strangulation again, and goes like that.

then go with your grandma or granpa and tell him-her to massage your neck, while doing this you will talk to him-her, tell him-her that tells you a story when you were little.

finally gave him or her a white flower.
