I'm 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 danger's 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 danger's 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 day's 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!?
