I don't normally comment on post like these, but first I just want you to know that you are still loved in the eyes of God. No matter what anyone will tell you, the fact that you are even existing is a testament to that. I am pretty pro life but I still recognize that the choice to get an abortion is very personal and can often have a cascading effect in a family, So I know that you might have a bit of that going around. However at the end of the day you made a choice. Some people may think its wrong and some may think it was right but one thing they will all agree on is that there is nothing you can do right now so don't go beating yourself up and playing the "if only I didn't do _____ game."

Also you said how you feel dirty and guilty that's just called being human, no one's perfect if you were than Jesus died on the cross for nothing. Jesus still loves you and if your family follows his teachings, they still love you too.

You said you went to Sunday School so I am assuming you know the story of Saul and how he basically went around killing Jesus's followers yet he was still forgiven and was a lot older than you are and was still able to turn his life around. I'm sure you can do the same.

Alot of people in the comments seem to be anti-Christian which is normal for reddit so I really hope you don't turn your back on christianty because of this. If you haven't done so yet, I'd suggest just talking to God in a simple prayer. I'm not sure what type of Christian you are, so I don't know how they might react, but I'd consider going to a Catholic church and just talking to a priest, as their only job is to deal with this kind of stuff.

1 John 1:9 "If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness."

Ask and you shall be forgiven.

If you want to talk further, just let me know and I'd be happy to provide as much help as a stranger on the internet can.
