Anxiety, how to deal with

The way to help yourself is to practice proper breathing and use the mantra "I can leave my body out of it."
• By practice, I mean the Buddhist type of practice where you do it everyday for the rest of your life.
• By proper, I mean breathing by pushing your stomach out to move the diaphragm muscle instead of attempting to expand the rib cage.
• By breathing, I mean inhaling through the nose, exhaling through the mouth while making an "O" sound and then closing the mouth and exhaling the remaining air through the nose while making an "M" sound (sounds like humming).
When feeling something isn't right with the body, say aloud "I can leave my body out of it" over and over again until the bad feeling passes. The bad feelings get shorter and shorter over time, but never go completely away. Then over time, saying the phrase silently to your self is all that is needed.

This method works whenever there is any physical symptom that a doctor can't diagnosis the cause. There are over a hundred symptoms for anxiety that mimic real physical problems that the doctor can’t diagnosis because there is no evidence of a cause (virus, bacteria or organ failure). In your situation (where many things have gone wrong in the past) there is sometimes no evidence of a cause for your symptoms.

Like all humans, your mind and body are closely connected. The mind thinks something might be wrong (because in your case many things have gone wrong) the body reacts and sends signals to the mind that something is wrong, the mind stimulates the body, the body sends signals to the mind that something is wrong and it spirals out of control. This circular cycle is broken by using the mantra "I can leave my body out of it" and practicing proper breathing.
