16 years old. Heart Attack?

[Fraid]

I should probably give some background information since every place i have asked say its possible but not very likely at all.

I'm 16 years old 175lbs 5,11. For about the past 6 months or so i have done nothing but sit in a dark room on the computer, doing my school work and playing video games. I occasionally go outside but not so often anymore. I use to exercise, lift weights, run. But none in these past 6 months. Experiencing this has made me want to start exercising again and getting back in shape. Because i am slowly getting fatter sitting here at the computer.
I am not in public school because i have social phobia. And have been really depressed with all sorts of things going on with my dad.

Recently i have started having chest pain, not incredibly painful or anything, not really uncomfortable either. Except one i had in my chest the first time. But it was not so painful that it would have woken me up if i were sleeping. I haven't had a tingling or anything in my arm, but i did have kind of a stab pain near my wrist. But you could rule that off to carpel tunnel since I'm on the computer a lot. I have a headache almost every day, a very dull one on the left side of my head. (makes me worry about tumors) and a light pain in the left side of my neck, really light. And only once, i also crack my neck a lot which i should probably stop doing.

The pain has also occurred on the right side of my chest, lower and higher up. My family has a history of OCD so i take every slight pain as a symptom as a good possibility as my mom says. So the fact that i felt a light pain at the top of my legs getting out of the shower today wouldn't be anything. And when i say light, i mean light. I wouldn't have even noticed it if i wasn't being all paranoid about having a heart attack right now. My Mom, being a nurse was talking with her co-workers today and they think maybe due to my severe anxiety it could be an ulcer.

If have any info or have questions please do so.

Thanks.

Have you had your cholesterol checked?  Doctors are now recommending children as young as 9 to have their cholesterol checked.  My cousin at only age 9 had high cholesterol levels.  With that being said, anxiety itself can cause chest pains and pains throughout the body.  If your blood pressure is normal and your cholesterol levels are normal, you should work on getting some sunshine and exercise.  It is amazing how much better a person can walking on a sunny day.

Based on your very low risk factors for coronary artery disease, the likelihood that your pain is related to your heart is extremely low.  I think that this is most likely some form of musculoskeletal pain.  I would recommend exercise or physical therapy.
