Father's day, depression, pregnant?

I am just DEPRESSED :(.... It's father's day and my dad is been gone for 2 years now (RIP). I just miss him so much..I have been crazy depressed before but my husband was always there to help me cope with the grief. We got in a little fight yesterday and I have been pushing him away since. He apologyzed and the whole deal but I don't feel like talking to him. I have been crying since I woke up this morning. Every soul I know is busy right now. There is no one I can call to talk to. I called that 1800- talk number this morning; cried, and talk my voicebox off in the lady's ears and it still didn't help. I do not feel like doing anything today. I just want to sit home all day and mourn my dad's death. I am pregnant and afraid that all this stress will hurt my little man but I just can't help it. I feel helpless. :'(. Any advidce of how to get through this day without passing out from all these tears and headaches?
