Dear
Welcome to HCM
We understand your concerns
I went through your problem description. You should ask your friend not too worry too much. The symptoms you provided, even though not exhaustive, might be leading to
stress related
anxiety. Anxiety related to stress always elicit such symptoms. Sweating,
chest tightness, feeling anxious etc should not be seen as problem itself. They could be symptoms related to physical and pathological conditions.
Before concluding the problem as stress related, do consult a physician and seek his advice.
Hope this answers your query. Available for further clarifications.
Good luck.
