My Hypothetical Family Situation

I am  eighteen years old and I am a single mother  of a three year old little boy.  We live in a small town.  The father of my son refuses to acknowledge that he is the father and will not take a paternity test.  So you can tell we receive no emotional or financial support from him.  All of my family is in New York and I only have a few friends her in Texas.  I was unable to finish high school because I was taking care of my son because my parents kicked me out of the house.  I currently was accepted on CCMS and and have enrolled my son into a preschool program.  He just turned three and in the last two weeks I have received numerous phone calls from his school discussing his aggressive behavior and how he runs out of the classroom.  The teachers have told me that he has a difficult time interacting with the children in his class and has many meltdowns were he screams.  They have a difficult time calming him down and he does not want anyone to touch him.  They say he is extremely smart when it comes to academics but his social skills are below average.  They also have a difficult time understanding him when he talks.  He mumbles a lot.  They want to schedule a meeting with them to address their concerns and see if this is the right center for him.  I am lost and scared of what they are about to tell me.  I always knew my son was shy.  Since I do not have a lot of friends my son is not around a lot of children.  His doctor says he is just different and goes to his own beat.  Really never understood what that meant. There has been times when we have gone to the park and to be honest it has ended in complete disaster.  Screaming at kids and fighting over the swings.  He has a difficult time sharing but he is the only child so I thought that was normal. So now I ask myself what do I do next and who can help us?

To my colleagues here are my questions to you:

• Have I given a complete picture of my family, or are there details missing that I should include in order to complete the assignment successfully? If so, what are your suggestions?
• Is this situation realistic?
• Are there any specific websites I should be reviewing with regard to learning about quality services and programs for my child and family in this hypothetical family situation?
• Does anyone have any thoughts, based on my specific family situation, that will affect the early childhood system I am creating?
