Hi,
Welcome to the ehealth forum and we are glad to lend you a helping hand. Your concern is regarding the nervousness that makes you sick. The symptoms that you have described seem like anxiety neurosis. It is a series of symptoms, which arise from faulty adaptation to the stresses and strain of life.
It makes sense to consult a psychiatrist as you might need medications for the anxiety and maybe a round of psychologic counseling. Treatment options include cognitive behaviour therapy,medicines like SSRIâs, benzodiazepines and psychological counseling.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
