Are you on any meds? I sleep with one pillow because i know i cant with two. Wish i could cos its more comfy but keeping your head fairly even with your body will be better for your breathig!!!!!!!!!!!!!!!!!!

It sounds like anxiety and it could turn to panic if you do not take some steps to deal with it soon and trust me from experience you do not want to go there. Anxiety is generally caused by how you improperly process thoughts often in regards to a physical sensation like shortness of breath. I would encourage you to look into learning cbt coping strategies. Cbt is great for panic anxiety and depression but you have to do the exercises everyday so it does take a lot of work and self discipline. It is self-help so you can do it on your own if you are willing to work at the exercises like the tea form. I still do the tea form exercise that I learned in the book by sam obitz daily and the thought processes that eliminate panic and anxiety do become ingrained over time but you have to do the tea forms everyday! Good luck and i hope this is helpful to you
