Hi, I do internet surfing regarding my problems am too health conscious. But know this is becoming a problem for me, lyk over thinking, and I dnt know from two days am felling light headed, dizziness, and it is bothering me alot. Do I have any problem in my brain or something I do not have any problem in day to day activity but could feel the stress in my mind. While sleeping and all. Are they any symptoms of any thing. If possible tell me whom I can consult regarding this.
