What am I still doing here...?

I have been lately very concerned on finding out what the hell I am still doing here. I ask this myself since I came back from a coma of 3 days. When David didn’t do the same, and decided to leave. I have since then trying to figure out what is the failed subject that keeps me here.
Can’t figure out. Three years later, I married. A half made man. I didn’t know he was not yet a full made man. I find miself now, married, with a 2.5 years old girl, 3 months pregnant, and my husband does not give me enough safety to keep my mind healthy.

Which makes me think, at some point, I gave the wrong step. I do not know yet if it was before, or after the accident. But nothing seems to be all right. At least not with him.
