Uneasiness in breathing. Breathing.

I was having a throat pain few days back, which had hard time swallowing, I took medicines from my family clinic results to pain reduced while at rest but its still difficult while swallowing. Later yesterday I realized that I am also having difficulty in breathing when I tried to sleep in afternoon. I had to consciously make an effort for breathing. I informed my doc and he said it's bcoz of acidity.I came back and Read it on internet that it could be related to anxiety or esophagus swelling or GERD. (It is true that I am into the heavy stress since last 2 weeks (since I m buying home and pressure from seller) so I thought it must be anxiety) I have been reading too much on net and now very much worried. I counted my breathing rate at rest and it came 17 and pulse rate 78 which found to be normal, but I somehow feel air is getting through nose is blocking at throat and not passing ahead(heavy feeling at chest). Please help me with my condition and how to get back my normal breathing.
