Increase pulserate. I wish to survive.

Hi , I'm diagnosed with covid in month of May last year, since then my pulserate is above 100. I took ivabradin tablet 5mg for 2 months. But it was giving dizzyness double vision during night, so doctor advised clonafit beta - 0-0-1 later changed to 0-0-1/2. I took ECG, 2d echo, d-dimer , TSH, Sugar test. Everything is normal except esr. Esr is 95. I have no idea what the problem is. I have changed diet plan. Intermittent fasting, rice once in a week. More fruits and rotis. Daily exercise of 45min. I could see the effect of tablet only untill morning, there after my pulserate comes to 100 above. I cannot afford much on medical expenses. I really appreciate if someone here advice me. What could be problem. I'm afraid to stop clonafitbeta. Recent ECG reports tachycardia and inverted T and 95 ESR. Lipid profile is normal, HDL is 30( not optimal), I have dependents  and I wish to survive. Thank you.
