The answer is no.
The fact that you think you're prepared to adopt a child when you are a child yourself, and have never had a child and don't have a partner, already disqualifies you. Foster children often come from severe, abusive, neglective, and tragic backgrounds, and will deal with trauma from these experiences for the rest of their lives. You clearly have not had any real life experiences or done any research about this. Very few people who have had kids, are married and have been preparing for a long time are successful when adopting a child--what makes you think you can give them a proper home? Adopting a child is not like adopting a pet--this is a living, often injured human being who will need intensive care, safety and stability to succeed in life, and, even in the best circumstances, have higher chances of having or developing critical, debilitating mental illness. By thinking you can provide them with everything they need, you've already proven you can't.
