What you need most is a feeling of peace. The best way I know that can bring peace to you is meditation. You don't have to be an expert to be able to meditate. simply site silently for a 20 minutes period, observe your feeling, don't judge it, simply observe. You will quickly regain your peace.
Anxiety comes from mismatch of subconscious and conscious desires. Mediation is a way to make you be aware of your subconsicous desires.
I hope this will help.
