hello, im 17 yrs old..i cant sleep at night, i feel stress and fast heartbeat. Everytime it happen, i cant avoid thinking bad things on my mind! but im trying not to think of it which is very hard for me to do!! at age of 12 yrs i cant sleep all night and even im trying to sleep in the afternoon, i still cant! i think the cause is im always thinking many things at night which is not good.
Then days past i feel sick, very tired, feel cold, fast heartbeat, and dont know what to do! i told this to my mom and after 3months , i consulted Dr.Ilagan, and said to check CBC, ECG , T3 T4, X-RAY, blood chemistry. and the result are all normal except my CBC, She said that i am anemic (ida). i take iberet 500mg that time and after many months i feel better and consult again to check my CBC and its normal But Dr. said to continue take medicines and i take that for 3 yrs. because all is normal. But i always feel fast heartbeat even result is normal.But that time i always feel fast heartbeat Now im 17yrs old i already test for 2d echo and result is normal But i still feel same before. I was thinking im depressed, and stress and i still cant sleep well.There are bad things on my mind hard to remove which made me sad. Does sleepless night, stress causes of fast heartbeat?
