I had this condition when i was just 16 years old. It is a inflamation of the heart tissue. I was in the hospital for about 6 months i think. then at home in bed for several months. Doctors then let me retun to school but no overdoing it. I could not walk anyhwhere and after school had to come home and go to bed. It took about a year and a half out of my life. but i did heal. Drs. said if i did not take real good care. I might not be able to carry a child. So my parents were very strick about following orders from the doctor. I am now in my 60's and have had thee children and never a problem with it since. So Please follow all the rules and you to will be well again. It just takes time.
