Crisis of Faith or Lack of faith in myself?

Lately I have been super depressed. My husband has been trying to get me to let go and let God, but I am having a very hard time letting go of my imaginary control on life. I recently started back on my meds (I take Celexa) but they don't seem to be helping this time around. I cry at the drop of a hat. I don't know if I am having a crisis of faith or if I'm losing faith in myself. But losing faith in myself would mean that I had to first have faith in myself and I don't think I've ever had that. I thought that I would be able to relax a little now the school semester is over and I passed all my classes, but no such luck. I feel overwhelmed with life. Maybe I'm just being a whiner. I don't know. All I do know for sure is that something isn't right and I can't put my finger on it. Will most likely talk to my doctor about either changing meds or adding to it. I need to spend more time with God but there just doesn't seem to be enough time in the day. There are so many things I want to do that involve my faith but because I never grew up with it, I always forget. For instance, I want to start saying prayers with my son before he goes to bed and I want to pray before we eat. I always forget until after and then feel crappy for not sharing those things with my son. He's only 2 but... Anyway, I just needed to vent and get this off my chest. I hope that I can figure out what's going on because it's putting a strain on a lot of my relationships, especially with my husband.
