From where I stand .the reason why you are ill and have a low sipirt is that you are very tired and still have not form a good habit.I firmly advise you to have a healthy and balanced diet.It is also very important to go to bed early.To keep happy and do more exercise will be very useful to you and I firmly believe you will keep away from your problem if you take my advice into consideration.
