Worried about Heart Problems: Seeking Advice

I’ve been having heart problems for a couple months, but they’ve been getting worse recently. I’m experiencing pain and tightness near my heart along with my lungs, elevated and noticeably heavy heart-rate/palpitation, random bouts of radiating heat and chills, trouble breathing, weakness, although starving, a complete lack of appetite, nausea, and so much more. I can’t go to my doctor’s for the next few days, and am really worried about this. I’m worried, because both sides of my family has history of heart disorders. I know I shouldn’t be jumping to conclusions without a diagnosis, but the only thing I’ve come across that matches my symptoms almost perfectly is Congestive Heart Failure. It seems that, recently, I’ve developed Central Sleep Apnea which also goes hand in hand with CHF. I’m very worried about this potentially being the case, and my mind would be put at ease if someone could disprove my suspicions.
