Preschool

Me and my husband were pudding my son into bed last night when he started to cry and tell us that he felt like he was different I asked him why and he said because he talks differently than other kids I asked him why he felt that way and he said the teacher told him he is different because he has a speech problem. I have had him in speech therapy for over 3 years and he has never expressed those words before. So this morning I went to school early and as I arrived I apologize for being so early and she then told me to go wait outside until the appropriate time to come in there's two doors in this classroom and there is another parent coming in from another door that she welcomed with a smile and a good morning why I was standing outside I feel as though this teacher goes out of her way to make me feel unwelcomed she didn't even say good morning to me or my son I was so pissed off I didn't want to talk to her and that moment about what my son had said the next night so the more I thought about it I decided I was going to pull my son out of school I showed up early to pull my son out of preschool and she didn't even say goodbye to my son or even asked me what was going on! this is very first time I've ever picked up my son Early! he was only in school for an hour. I really don't know what I should do! he only has two more days before his permanently kicked out of preschool This is the only preschool in the area where I live! He really needs speech therapy and social interaction I feel really frustrated I do not know what to do I literally feel like I'm being bullied by this teacher this teacher yells and screams at students she has no patience she has no personality she has no enthusiasm when it comes to the children in her classroom and when I did pick up my son from school early she was sitting at his table with a child while she was on her phone! I really need advice on what to do!
