First of all, thank you for your service. Next, it appears you have experienced the loss of multiple key loved ones in a short amount of time. Trust me, this will put just about anyone in a state of depression. It sounds like you have a wonderful family. I would be careful with the drinking - it tends to compound our problems rather than help fix anything. Please contact a pastor who can help with your marriage and general well being. This life can be very difficult at times and there is nothing wrong with asking for some help. Hang in there!
