You are obviously not alone here. I remember those days of feeling like I couldn't breathe and had to force myself to take deep breaths. While I was in the throws of addiction with my ex, i had to travel alot for work. For some reason, that just made it worse. I thought being in a different environment would help. Some times it did but many times it just made it so much worse to be away from my daughter and the things that I loved the most. You will get through it. It will get easier.
