You really should see a doctor. Along with it you can also do some affirmation like " I'm totally healthy in everyway" You have to forget/ignore about your illness while doing it. Should have a strong will,desire to get healthy,to get back to normal condition. Just TOTALLY pull the thought out of your mind that you have bad cold/illness,whatever. While doing affirmation you should know that your affirmation is really doing its job,it is working and you should be willful to be healthy.
