Upper Abdominal Pain. From anxiety!

I am experiencing occasional upper abdominal pain during the afternoon till evening. Also palpitation and higher heart beat was also observed. I consulted a general physician regrading this. My BP was observed as 150/80 and PR 115. The medication given to me have been listed above. Blood Sugar (FBS/PPBS) ,Lipid Profile , T4/TSH tests were also done and was  observed normal. . I lost my father two weeks back due to sudden cardiac arrest and am quite tensed for  if my and other family members health. I am suffering from anxiety regarding this also and can't seem to take my mind off my father's sudden demise. So I am not sure whether this symptoms are indicative of any heart problem. Please suggest if I should visit any cardiologist immediately and get others tests done  or whether this may be muscle pain only. There has been a lot of stress on the body in the last 2 weeks also due to all activities related to the last rites.
