I really really want to have an abortion
Are you sure about this? What makes you want to have one so badly?
I'm already a mother of a child and I don't want to be a pregnant woman again.
Abortion can be such a touchy subject for some. If you feel 100% in your decision, it is okay.
My family will be happy about it.
I understand how you feel, but you should do what you feel is right for yourself and not anyone else. Don't let your family play a role in these kinds of decisions. do what will be best for you and your well being.
