Anxiety always effects badly. The condition you are expressing has happened to me already. I was suffering from same condition and it really hurts. Then I visited my doctor and I told her my condition, she prescribed me to take Disprine (plain) dissolved in half glass pf water. It effected really good on me, but this is not some permanent thing you can do to get rid of this pain, major problem is anxiety attacks which are damaging your health and my doctor says it is something you can't cure with medicines. It works with your nerves and brain and it should be taken care by yourself. I don't say that don't take tension, because I know its not something that is in your hands. I will only say try to avoid tensions. Try to make your approach positive and remember, you always have to do one thing in your favor, just flush out bad memories and hurting things from your brain. don't keep on thinking about them.
It seems you are quite touchy about happenings. being sensitive is good, but being over sensitive is not good. Just think about one thing dear, Do people bother to think about your pain after they torture you, definitely 'NO', then why do you keep on bothering you for them. Be happy to show that you damn care and you are happy in your own life.
I hope you will try to manage that anxiety yourself and don't ever think of taking any sort of drugs or sleeping pills.
Take Care!

Stress can weaken your immune system and make you more prone to diseases. It can also raise your blood pressure and heart rate. Stress can also cause cause headaches, abdominal pain, and poor appetite. Stress is also a risk factor for heart attack.
You state you have high stress and anxiety. Most of the symptoms that you have, the chest pain, nausea, headaches, and feeling short of breath can also occur during a panic attack. In addition you can feel lightheaded, have tingling hands, feel unsteady, shake, and feel like you are going to die.
My suggestion to you, since these symptoms are obviously interfering with your life, is for you to visit your doctor. They will do a history and physical. They may recommend that you also see a psychiatrist. If it is determined that all of your problems are medical in nature, recommendations will be made for how to help you. These suggestions may include diet, exercise, or medication. If it is decided that panic attacks are causing these problems then you will have to decide with your psychiatrist whether counseling, medication, or a combination of both is likely to work for you.
Hope you feel better soon!

Yes. Stress can make you sick and it can even kill you. It impairs your immune system and speeds up the aging process. A lot of serious health problems are the result of stress. I would recommend you practice deep relaxation. Meditation feels good and after I started doing it on a regular basis my seasonal allergies went away. During allergy season I no longer have any symptoms. Meditation also gave me more energy. As a result I sleep less and have more energy throughout the day.

While meditation worked the best for me exercise also helps to reduce stress. You might want to start a relaxing hobby. As a hobby I take photos of wild animals and nature scenery.
