Where did I go?

Where did I go? This is a question I have been asking myself alot lately. I am not the person I used to be. The one with the attitude, the spunk, the charisma to cheer anybody up. Over the past year my health has not treated me fairly. Some of it could be my fault and some of it is just the nature of the beast called diabetes. I no longer have that joy in my life. I no longer want to be the bright spot in someone's day. I no longer care if I take a shower. I no longer care about alot of things. I know all these are signs and symptoms of depression. I am on medication and I am not about to go jump off a bridge...so don't get real excited. I just want to know where I went. I want to know where the thirst for God's knowledge went. I want to know where the zest of being a mom, a friend, a sister, a daughter, etc...where did all that go? I am not able to work right now. I don't know if I will ever be able to work again. All I have ever known is to work and work hard. Working and making a difference in people's lives beats the heck out of working to clean a house. I love my time with my baby boy who is 10 years old. My oldest has moved on. I feel unappreciated, unvaluable, walked over, stepped over....these are all the feelings I felt when I was in school... I don't want to feel this way anymore, but I don't know how to get out of it. I want my life back...I want my marriage to have that spark again...I want my children to say, "Oh mom supper was great!" Is this too much to ask for? If it is then this is not what I signed up for!
