Sorry to hear about your situation SD. And thanks for all that you do! I was military myself, and have a lot of respect for those who serve in the armed forces. Don't beat yourself up over feeling sorry for yourself from time to time - it will come and go. Some days will be good and others will be hell! When everyone describes this as an emotional rollercoaster, they are not kidding! It's enough to make you question your sanity that's for sure! And yes those 180's are for YOU, man! The only thing you control at this point is how you will let this affect you, and how you are going to overcome this! I have been using the phrase "sink or swim" a lot. No matter what happens, you will be a stronger person from this - just keep your head up and keep marching through this.
