I have realized, that I am gradually starting to lose my intelligence. This may be caused by several factors (such as spending lots of time in front of a computer, inhaling smoke - passive smoking-, not exercising, stress, school pressure, extracurricular competitions that require extra hours of reading, lack of sleep etc.) which I can not change immediately. I would like to face it drastically and get back the intelligence I had lost all this time. I could say undoubtedly that this is a psychologically painful situation to cope with. I am starting to lose my self - confidence and I feel useless. I feel like I have failed in life and I will never be able to think clear again. What could I do?
Thank you,
