It sounds a lot like low blood sugar/hypoglycemia to me, but I am not an expert. I have a very good friend who naturally has a high heart rate. It can cause an enlarged heart over the long term (think about how we exercise muscles to make them bigger - a high heart rate exercises your heart and makes it bigger). Anyway, he is on medication to slow it down (I think he's about 125 unmedicated/100 medicated).
Anyway - I am sorry your family is not supportive - that stinks. A lot of people are resistant to change, and overprotective
Hang in there!!
