### input:
Im a 23 year old female and have been considerably healthy my entire life.  I am currently in the military and about a year and a half ago I came back from my first deployment.  I was not in dangers way and I was not exposed to anything overseas.  I was back for a few months and began feeling exhausted.  I was sleeping 12 + hours a day but I was able to function through the fatigue.  I got back from my second deployment about seven months ago.  Same thing.  I was not in dangers way and I was not exposed to anything overseas.  I am so exhausted now that I am falling asleep at work.  I have never done this before.  I was diagnosed with sleep apnea and have been using my CPAP machine but it is not helping the fatigue.  I am on Celexa currently for depression but I really do not think that I am depressed as it is something that I have been exposed to and dealt with throughout my life.  I am an avid runner and always have been but it is near impossible for me to get out there and run anymore.  It feels as though it takes a days worth of energy to get up and use the restroom some days.  I have had my thyroid tested and have tried vitamins.  I feel that everytime I see someone they want to tell me that it is depression.  I can assure you that this is not depression.  This is painful and exhausting.  I get pretty bad headaches on a regular basis and I have always urinated frequently.  What is wrong with me!?

### output:

My dear friend.I would like to tell you 2 things. Please listen carefully. First is depression doe snot men that you should be sad always. It is something more. If you feel lethargy no interest in any works and feel tired exhausted without any apparent reason. Even this is depression.it is caused endogenous depression.2nd thing is that you have to keep faith on one doctor mostly a psychiatrist, and you need psychotherapy for coming out. There may some issues which may be in unconscious mind causing depression. So please visit and continue treatment. I can understand it happens, but you are strong enough to tackle it too.
