Deviated Nasal Septum. This condition?

Ever since when I was around 11 years old I have been experiencing fatigue and lethargy throughout the day whenever I stay idle (for example in class rooms) which resulted in stopping me from leading a vigorous life and I also found it difficult to fall asleep. Whenever I consulted primary doctors they told that I'm having this problem due to anemia or other related ailments. But all my test results were moderate and I continued to have these issues for many years. Later, a few years ago I was diagnosed with nasal septum deviation. The doctor at a govt. hospital suggested that I go under medication first and if the condition is not cured then undergo a surgery.  I was only prescribed certain suppressant medicines and nasal spray continuously which were of no help and had side effects. So I stopped it. I am still having those troubles which causes me to lose the energy all day. Can septoplasty cure this condition? Plz suggest specialists near me and govt. insurance empanelled hospitals.
