Ho hum

I'm not sure what has been going on with me lately, but I have not felt like myself in a while. Not sure if it's winter blues, postpartum blues, being overwhelmed with everything on (including being a stay at home Mom to 2 boys) or what. That is probably enough, but I just feel like I'm losing my grip on sanity. I can't seem to make the things that I want to happen happen (like get my 3 year old to sleep better and get my 7 month old to nap by himself), etc. Life just seems really hard right now. And I feel like I have no right to feel that way, because I am so blessed. God has no reason to bless me, but He does. And I feel like I should wake up happy every day, because I have a husband who loves me, 2 beautiful, unique children, the knowledge of the truth, a beautiful house to raise my kids in and parents who love us. What more could I need or want? Why am I not feeling happy?
