what to do when the hoarness starts

I have had hoarness for about two weeks. I couldnt think of any reason why this was happening to me.
then I started researching about it and discovered that it can come from Heart Failure and enlargment of the heart.
I am very scared and worried right now. I cry a little bit then I go through all my legal documents. I am preparing or trying to prepare for death.
I dont know if the doctors can help me. I do have medications for my heart and the doctor took me off of atenolol because HR was too low. I am only taking amlidlopine and eliquis, Vitamin B12.
IWE just had a snow and it is very cold. The snow is metling and freezing overnight. It is going to be difficult to get to the clinic.
I have a feeling they are going to send me to the hospital. I feel alright and at the moment, no wheezing or couging. I do try to clear my throt but cant cough up mucus.
Anybody had trouble with those symptoms?
