My friend is suffering from stress and depression ,she is also suffering from migraine and sleeplessness from last 3-4 year ,doctors are keeping experimenting on him by changing medicine strange thing is that her all reports are normal including mri report,
She is taking sleeping pills to sleep,she takes 20mg zolbien without this she can't sleep.
So I want to know the treatment that makes him better.

If your friend is suffering from stress and depression, you should try to find out why and talk to him or her. Maybe they just need some friendly advice.
