So tired. Always.

I can't take this anymore.  I feel like I'm losing it.  Doesn't matter how much I sleep. 4 hours, 6 hours, 8, 10, 12 hours...it's always the same.  I'm always SO tired I can barely function.  It's having such a huge effect on every part of my life.I'm shaky all the time.  I don't go out with friends anymore because I'm too tired.  I don't have a social life much anymore because I spend my weekends sleeping and every day after work taking naps.  I hate it. I don't know what to do.  I'm trying to make doctor appointment, but my work still hasn't sent me my insurance packets.  I don't even know what the doctors can do.  Go to one appointment just to make another appointment for a specialist just so they can refer me to someone else so that they can do  tests that take two months to get results back just so they can tell me I need to see someone else just for them to tell me nothing is wrong with me.  I'M SICK OF IT.   I'm pretty sure it's sleep apnea, but I have no way of knowing for sure.  Does anyone else deal with this at all?  I hope I'm not alone.  I feel really alone.  It's making me depressed.  I need help.
