Hi there! This sounds a lot like social anxiety. The problem with anxiety is that it affects you physically as well! Which can, of course, make things more embarrassing. Seeing a professional like a regular social worker or therapist could help you learn to control these issues. Physically, there are little tricks that can help. Deep breathing triggers the relaxation response in your brain, using the sympathetic nervous system. Being healthy helps a lot! Have a good diet, caffeine and sugary foods will make anxiety WORSE! Hours before your interviews, challenge your worries so that you won't worry when you get there : (Is my worry realistic? What is the worst thing that could happen? How could I handle it? Is it really likely to happen?) If you are up at night because of your anxiety, natural medicines/supplements could work. A good cup of Sleepytime Herbal Tea will calm you. It usually has valerian root or melatonin in it, both supplements you can buy in pill form. That's all the advice I can give you but PLEASE DO NOT resort to using drugs or alcohol to help with anxiety! You probably already know but just a reminder :) Good luck!
