19 year old with various problems.

Doctor this started in july 2017 i started having very big burp and went to a doctor who just said that its just tensiin(preparing for jee) after few weeks i started having chest pains and panicking went to a cardiologist gad an ecg , echo ,thyroid test(as well as pancreas & liver test) all came normal except a little high amylase.still chest pain persistent All doctor said its nothing After a few week i got a little blood while pooping so went to a gastroentrologist.ge did an endoscopy and said a minor haemorrohid and gave me medicine for it to take for two month.He also said its fine.Now i am starting getting pain in my left and right hand that comes suddenly and goes.Is it all anxiety???the hand pain symptom developed just days ago And i constantly worried about my heart.Whenever my heartbeat i start panicking and checking my bp.My father now doesnt want to take me to doctor as he says its all in my head.I am also very skinny and rarely exercuse because of studies.
