How to ease bad anxiety due to throat tightening and mucus?

I get mucus in back and above of throat. I had a deviated septum surgery. My breathing got much better with occasional blockage still, however, as time has gone I have a hard time sleeping at night as I feel that there is mucus that I cannot clear in the back and above my throat with tightness of throat. I have been using saline, I use 1 spray of dymista 50mcg in the morning and night and 2 sprays of Ipratropium bromide 0.03% and occasionally Afrin. I also take Pepcid complete 2 in the morning and night. I am getting anxiety at night
