frustrated scared...single mom

It is never a good idea to place a child for adoption under extreme stress, which is what you are facing now. You sound like you need support to be a parent... guidance from someone you trust, a babysitter so you can have some alone time, etc. Raising a child is really tough in the best of circumstances, it is harder on your own. Before you place, please, please, please, get some assistance. There are counseling and parenting programs for single moms, there are online support groups, there are parenting programs and moms groups. Is her Dad helping with financial assistance at all? If not, take him to court. If you need any referrals, pm me. Frustration and being overwhelmed can be addressed. It is not a good reason to place.
