I had an abortion and I feel like it’s controlling my life.

I had an abortion last July, I feel as if I regret it and it’s just making me in my opinion and the people around me just an overall bad person. Since having it I have not felt the same at all. I think about it constantly, I have a 2 year old and I feel like I’m just completely withdrawn from her now. I hate feeling like this. I wouldn’t say that I necessarily wanted to have an abortion but it was what was best. I don’t want to continue feeling like this horrible half-butt mom. I’m not sure where to even go from here.
