if you're already a single mom and people are critical of that, well, there's really nothing you can do. i've always hated the phrase, "living well is the best revenge", but God's word almost validates that. well, not the actual revenge, but that our response is to be obedient, walking in the light, and serving as we are called to, trusting that He will supply what we need and be our comfort and protection.
if you weren't expecting mockers, judgment and lack of support, you need to read that bible again. ; p that doesn't mean there aren't people who will love and support you. i would encourage you to find a body of Jesus-following, bible-preaching believers (a church body) and get involved.
i don't think there's anything wrong with choosing to be a single parent if you can fulfill God's laws doing so and believe that you are called to that (i.e. adoption, foster care, etc) . i don't think you should make that decision lightly, but over YEARS of praying and preparation. honest self-evaluation is a necessary part too, checking both your motives and your ability to reasonably provide for their needs.
however, i do believe that it takes many (i.e. "a village") to raise a child, and i would encourage you to consider that as well. while you may not receive the credit or pick the opportunities for your role/contributions always, if you have a desire to there are many, many kids in this world who are dying to have someone care about them, love them, encourage them, and so on. further, there are COUNTLESS ways for you to contribute to the lives of young people. : )
while i'm not sure if my response covered your OP query, i do hope you'll come back and clarify. : )
