Hi Tracy,
 I'm Cilla from SW Illinois (USA) & have COPD/Emphasyma & Heart Problems (tho not the same as yours) among other things.  I'm on oxygen 24/7 plus a ton of other meds.  You are so very young to be having these problems & my heart goes out to you & your young family.  I hope you like our group & I look forward to getting to know you.  The friends I have made here have seen me thru some really tough times ~ it's so much easier to relate to others with chronic illnesses.  There is tons of information on the left & always feel free to ask questions & hopefully one of us  will know how to answer or, at least, how to look for the answer.
 Hope you are having a good weekend.
 Cilla
