single mom considering adoption for my two year old

It does sound like you are way overscheduled and stressed with too many things on your plate. Before making a rash decision to place your child, I would see if reducing other obligations, as you plan to do, will help. School and work are hard enough to do on your own without a child. See if you can get some kind of respite support and cut back on the internship and the job. Get yourself through school, then you will be in a better position to get a good job. Does your school offer some kind of assistance to help single moms? At the least, they should have counseling available to anyone, most likely free of charge. Are you getting proper medical treatment for your depression and anxiety? Managing that will also help. Do you know other single moms through school or in your neighborhood? Perhaps there is an opportunity to form a support system where you can help one another. Good luck with everything and keep us posted.
