If your talking about a panic attack, they usually last a few minutes. You may have trouble breathing, sweat, or have chills, shake, have a rapid heartbeat or have feelings of doom. taking deep breaths can help to calm your body down and loosen your muscles.

spiritual healing and reiki can help you massivly
as can massage and no your doctor will not generally tell you about this here is why
what is paramount is to choose your healing route—— carefully– be really aware that the conventional treatment for this can be horrendous and you can go on for years with no improvement and massive damaging detrimental side effects from meds . do read this very carefully and try and understand the principles behind what is being said .
Evaluate all of this info well –this info will save you years of suffering —years if you apply it ..
This will educate you on our health care system and its dire limitations
All treatment recommended by the doctors should be tested and approved and quite rightly so.
That makes sense right .it costs millions to test and approve treatments because of the possible damage to people..
Drug companies Fund most research and will only and I mean only look at treatments, which show the promise of good deal of a profit, –they will actively dismiss any therapy which does not have profit potential— thus your doctor will only recommend therapies with profit in them.
Despite the fact that some of these other therapies mentioned do have overwhelming benefits some, which have saved needless amputations, needless pain and trauma, and much loss of life. Drugs are not the answer for depression with mind altering chemicals or any other mental illness. This is a fundamental principle and unless you grasp this fully –you could /will have years of suffering ahead of you .
This does not help you though when you are ill and suffering—not hearing about therapies which can help from a person you look up to and trust Have you heard your local doctor recommend, Massage Spiritual healing, Herbs, Light therapy,Colour therapy,the violet ray therapy, Osteopathy, Electrical Frequency devices.
