Good day I am a female aged 30 years turning 31 on 31-08-2019, I have a problem of being nervous and anxiety out of the blue and also I have a headache that does not go away and its itching. This anxiety and nervousness is taking over my life.

Anxiety & headaches. What we don't know is what steps you have taken to address these symptoms. If you haven't been medically assessed yet - that would be a good place to start. There could be an underlying medical issue or this could be primarily psychological in nature. Once the condition is determined, than a treatment plan can be developed for you. Be well.
