Hi and welcome to Healthcare Magic. Thanks for your question...
It is possible that your symptoms could be manifestations of anxiety. However, headache associated with nausea / vomiting and visual disturbances may be indicative of a Migraine
. Moreover, the stabbing pains in your chest also seem concerning. So, I suggest that you have a proper evaluation done by a doctor, including a thorough physical examinations and basic lab investigations.
like breathing exercises, progressive muscle relaxation
technique, yoga, etc. can all help in relieving stress. In addition, you can seek the help of a psychotherapist to guide and help you learn better coping skills, stress management
techniques, etc. There are also certain specific forms of psychotherapy
like Cognitive Behavioural Therapy (CBT) which can be quite effective in dealing with anxiety, stress and negative thoughts.
Wish you all the best.
