Feeling overwhelmed

I'm feeling so overwhelmed. This is my first pregnancy at 38. I so want to be excited about it but the circumstances are so difficult. The father, who was the first to want to try having a family, has shown little interest in me and this pregnancy since I told him. I want children, but I don't want to do this on my own. It's not what I signed up for and I don't have anyone else I can depend on.

I feel like what should be the most joyful moment of my life has been tainted and ruined. I'm scared. Scared that I'll become angry and resentful of the whole situation. Scared that I may not feel the joy I should when this child is born. And ashamed to tell my family that I was foolish enough to get pregnant by a man I can't depend on
