It hurts to know, it can get worst

As i lay here in the dark i cant hold my tears from flowing down my face. At 33 i feel ashamed of myself. I have a 15 year old daughter whom i love dearly and here i am again.....A SINGLE MOM to my second child. Im so hurt i can feel the knot of pain in my stomach rather than feeling this miracle growing in my oven. Im miserable and I don't want to be like this. Please help me.
