Your palpitations, sweating, breathlessness and chest-side discomfort need a medical assessment rather than being assumed to be only anxiety.
Thyroid imbalance, anaemia, rhythm problems, reflux and anxiety can overlap.
Please arrange an examination with pulse/BP and an ECG; carry any thyroid reports and medicine details. Do not self-medicate.
Go to urgent care now if chest pain is severe or persistent, you faint, have marked breathlessness, weakness, or a sustained very fast/irregular heartbeat.
