Chest Pain or Anexity. Some time back!

Hi Doctor I have a history of anxiety issues since 2 years But it was under control, I was not taking any medication for a long time. But for the last 2 3 weeks, I have been getting pain left side and mild chest tightness. Have done 2 times ecg one in Aug and one Oct which came normal. Have done body check-up, which comes normal except vitamin b12 and d3 deficiency. For which I am taking medication. But in the last 2 3 weeks I have been more getting anexity or this is heart pain I am not sure. As per cardiologist, I am taking ciplar 10 on alternative days, starting only this week and also taking vanxit for anexity. Getting good sleep for 7 to 8 hours. But this morning, after breakfast, my heart beat went to 122, and then I took a ciplar 10 for one hour my heart beat was above 100, and then it came down. Sometimes I feel wired things in my heart and sometime normal. Also, there is feeling I will be fainted and more anxious. Please help. Attached is my report done some time back
