Sometimes don’t you wish that you had the ability to travel back in time and change things that have happened in the past? – I know there are times that I have felt that way.
Yes, you were technically a mother. However beating yourself up emotionally over the past won’t help. Unfortunately it is impossible for you to go back and undo your abortion. However it sounds like you are still in pain from the experience. Perhaps you should look into Project Rachel or other post abortion counseling which might help you to deal with some of the pain from your experience.
You can learn from this experience. Next time you can make different choices and you can still be a good mother in the future.
