Our oldest daughter who became part of our family as a teenager was born into a really bad situation which got worse, resulting in abuse to her in many different ways - it's nothing anyone would have chosen for a child, and about as far from an ideal childhood as is possible to be. Even so, she doesn't regret her life and very definitely does not wish she had been aborted instead. If she had been, not only would the world have missed out on the amazing person she is, but her daughters (who were also born in less than ideal circumstances) wouldn't be here either.
You wrote, "it makes me cry of the thought of abortion." You are regretting it already - even the thought of it - it will only be harder and sadder if you follow through and end your child's future.
