I Have Heart Problems

I think I'm developing heart failure!I have spent the last 20 years in bed due to my schizophrenia For 10 years ever since I was pregnant with my youngest son I knew something was wrong...I thought I had central sleep apnea due to shortness of breath and poor circulation. Then in 2010-2015 my tummy began to grow large while the rest of me stayed small, I developed rapid heart beats, where my heart would beat fast, lightly flutter, or wobble, and pause....I had a holter monitor and they recorded an arrythmia and a 2 second pause. Then over the last few months Ive been coughing up a mouth full of saliva, then over the last few weeks my muscles ache. Then last night I coughed up a mouthful of frothy saliva and had shortness of breath.....like my lungs are filling up with fluid and Im not getting enough oxygen.....I have a doctors appointment today for something else....but maybe I should just head on down to the ER....Like I'm fine now other than a sleepless night....Oh yeah and a spirit came to me the other day and told me I was dying as it sang to me...and I don't know if it was an angel or a demon. I hear both.....but ever since 2010 I could hear a choir of Seraphim angels sing praises to God, its the solo spirits that tell me that I'm dying that I have problems with. I just have to talk to my family doctor first before I go on self diagnosing myself...its just that these symptoms just fit heart failure. Who knows it could be something else I don't know...but I am giving my children all of my love and making the most of life if I can.
