Chest pain by heart scared of heart disease or heart attack

4 years ago I would have pain on my left side of my chest when I lie down on it and I still have that today it would feel like a bruise but  as if someone is pressing on it . I never knew what this was . I have anxiety I've had it for about 6-7 months and I've always had chest pain but it would be in the middle of my chest now recently I'm having it on my left side where my heart is and I'm not even lying on my side anymore because I know it will hurt if I do so I'm scared that ii m having heart problems I don't know what it Is can anxiety cause sharp pain above the heart or around that area? Or is something wrong with me? I don't really eat nutritious food and I haven't really exercised in about 2 and a half years because I'm scared of the outside world so is because of my lifestyle is it making me like this? I'm just really scared I'm only 16 and I don't want to die of heart disease or anything bad like that.

I can’t tell yo I what I this but I can tell you you are not alone as I have had chest pains all the time for years but especially the last 6 months. I’ve had many heart monitors and scans and they have all come back fine. Go to the doctors to be reassured x

Anxiety is a crazy thing! I’m not a professional but have experienced panic, anxiety, and depression. The pains can possibly be from anxiety. With anxiety you tend to hyper focus and can overthink yourself into a tizzy!  Been there, done that! Is it possible for you to go to a doctor, clinic, or therepist? Can you talk to family or friends to help you? I know it’s scary, but you have to make yourself take the first step in order to feel better.  And talking to a professional will give you peace of mind.  Don’t just sit there and be scared of the unknown. Take control and get the help you need. You have a long life ahead of you and you can definitely make it better.  Anxiety can be treated! 

It's just a little scary because it's always mild pain around my heart area and it scares me  can anxiety cause chest pain in that area?

Absolutely.  Not saying that’s exactly what it is, but anxiety def could be a factor.  When you have anxiety, you might not realize how tense your body is. And your breathing can be off from anxiety. Which can cause tight muscles in your chest.  Once you feel that, you hyper focus on it. This is normal with anxiety. If you can go to a doctor and tell them everything you’re feeling, it will give you peace of mind to know what you’re dealing with. Keep strong. 

OK thank u for your replies it makes me feel better
