My husband has always been a big cut up, laughing, carry on, being silly person. We have been together since high school, almost 11 years. Married for 8 of those 11. The past few months he has been down, lonely, and ill. He never laughs anymore. Me, or another family member can say something to him and while it is funny, he just replies yeah or something short. I have tried talking to him, writing him a letter, and he responds I'm fine. He has recently lost a lot of weight due to sugar problems. Don't get me wrong he was great before but now he is pretty hot! Help me help him or is there something I am missing.
