Is school in the future?

I guess at some point M will be going to school right? I'm just not so sure about now! Why am I talking about this you ask? Cuz tomorrow morning we have an appointment to meet with the school district program about where to place M. Right now she's in the Early Steps program, but when she turns 3 the school program takes over. She is over 2.5 now so we have an appointment to see how to transition her into the new program.
I am so beyond nervous, I don't know what you would call it. I half want to cry, half want to curl up in a ball and forget this is about to happen. Why? I'm not 100% sure. I guess you could say cuz I have know clue what they will say, then add in my own fears for her, and what I feel she needs, top that off with not knowing if they can fill what I would love for her to have. N's eval wasn't this bad, I sort of know he would go to a school(the whole 5 full days was a shocker), but I also know that would be best for him and he would love it. Which he does! M, 1yr ago, I though she would be ok with school at 2.5yrs old. Now I'm not so sure, I don't think she'd do good without me for that long. Trust me I think she needs some time away from me and with other kids more, but I don't think she could handle being without me for that long. I know that sounds crazy, but she depends on me for so much, help get her dressed, calm her down.....I just don't know. Then add in that she finally got OT back, how are they going to work that? She really needs it. I'm just so nervous I guess we will see how it goes.
