Can you be forgiven after having an abortion?

I had an abortion coming up to 3 years ago and have lived with the guilt and regret ever since, its so hard as I have a 4 year old I see her playing and I just get washed with guilt and so much regret, I am a catholic and I can't bring myself to see our parish priest as I am so ashamed, I don't even know if I could be forgiven for such a sin as I don't feel like I should be. I hate myself for what I did! Is it possible to get past this in the eyes of the lord?
