Son's school made me cry..... Again😭

I was worried about my son going to high school because they wanted to take him out of special Ed and put him in regular classes. He has autism and I was so terrified how he would do. I got a call from his English teacher telling me he was doing so well and how amazing he is. I picked him up from school today and saw one of the paras who go to both the high school and middle school. He said hi to me. He's at the high school certain days and says hi and talks to my son a lot because he used to be his para. He told me at the beginning of the year my son sat with him and for lunch since he would help with lunch duty. Now my son goes and sits with his own friends. He said to me "I've known your son since he was in 7th grade. He is a completely different child from middle school. I see his confidence shining. You did that mama. Don't forget it. He's flourishing because of you." If I was crying when the English teacher called I was BAWLING now. My son was so confused at why I was crying and I feel so silly 😅
