After reading ur post...I wondered...what makes you happy? Do u have anything in your life that makes you truly happy? Passions, friends?? Maybe you need to spend some time focusing on yourself, fill your life with things that truly fulfill you. Perhaps some counselling to see what you are looking for in a relationship and help overcome ur Marriage. Perhaps a trip to your family physician will help. Depression can be sneaky...I know from personal experience, sometimes you can sink very deeply before you realize what is happening. It's very hard to care about others when you are not well. Take some time to figure this out. I think you need to be the priority in your life right now. And please get help if you need it. Your loved ones will thank you for it. Take care.
