Dizy and Anxiety. This is not serious.

Since lockdown I'm anxious about my health. It all started with daily loose stools once a day. Now my symptoms of anxiety increased like anything and it's worst. Whenever I read any health news or doing some diagnosis I'm getting rapid fast heart beat and chest pain. Checked with all health reports all are normal including blood sugar and cholesterol ( Total 180) and Triglycerides (234) are slightly higher as mentioned by doctor. ECG was also normal and my cardiologist told it's all bcoz of my anxiety and he prescribed ciplar 40 (half tablet) every night after meal along with lipicard 160 for triglycerides. Then Etizolam 0.25 mg after meals in morning. However I'm taking only ciplar and lipicard on regular basis. Even after taking for a week now feeling dizzy sometimes after eating and somewhat wierd sensation in my left arms and jaw areas but still I don't have any breathing problem. I'm afraid and anxious a lot. Please let me know if this is not serious.
