I'm new to this forum, and medical forums in general, so I'll start with some history on me before I get to my situation.

I'm 18 but I'm overweight and eat unhealthy. I was very inactive but have become more active lately, lost rougly 30 pounds and have probably 50 to 70 pounds left to go, but my diet can't change because I do not provide for food in the house.

Heart disease and heart attacks run on at least one side of my family, and my grandfather ands great grandfather on my dads side died in their either in their 30's, 40's, or 50's of heart attacks.

I don't smoke, drink alcohol, or do drugs, I rarely drink soda, and rarely have caffeinated beverages or foods. I do have asthma and take albuterol and aerobid.

Lately I have noticed that my heart does not have a steady beat. It will beat harder when I breathe in even though I'm not struggling to breathe, and slow down a lot when i exhale. My heart rate when sitting changes from 72 to 86 BPM quite often. I also think my heart may be skipping a beat every so often.

Is this something I should talk to a doctor about? Could this be a sign of heart trouble or are changes like this normal?

BTW, it's been happening for months, but I have OCD ( been diagnosed with it ) and Paranoia ( haven't been diagnosed with this, but it's obvious ) and I feel paranoid around doctors and my obsessing over this just might be another thing I do because of my OCD.
