Can anxitey disorders and colds, viruses or other bugs agrivate each other?

Clear link: Any disease would have an impact on your psych. If you have an anxiety disorder, that will become worse and make the symptoms/discomfort feel worse. On the other side, if your symptoms are getting worse and confirmed by family and/or friends you might need to see a health care provider, since you will need treatment for that specific disease.

Fighting multi-wars: Anything that competes for or depletes your body's resources can leave you less able to withstand another attack or demand. So, you are more vulnerable. Also - your experience of the symptoms may be worse. This is a good reason to avoid, reduce and manage anxiety and live a healthy life style. CBT can teach useful skills. Best!
