Hi vir_maha,
What is your nutritional intake like?
Improving the selection of food I ate helped me overcome some anxiety problems. Why not try these steps and see if they work:
• Increase your intake of fruits and vegetables
• Substitute refined foods with whole grains
• Take a vitamin B6 supplement
• Take fish oil supplements (this step alone made a monumental change in my life)
This page has more details on the impact of nutrition on anxiety.
Also, make sure to go outside every day. A lack of vitamin D can cause depression and anxiety problems.
