Feeling guilty for having abortion after having my first baby

So I had an abortion when I was 18, which was 12 years ago. I wasn’t ready for a baby, I was living with my parents and had a low paying job and was in my first year of college. I felt guilty about my decision, but as time passed I thought about it less and less.

I had my son 6 weeks ago and I am so inlove with him. But I can’t stop thinking about how horrible I feel that I aborted my first pregnancy. I know the amount of love I have for my son is the same love I would have felt if I had gone thru and had my first baby. But he isn’t here because of me
