I feel bad because I told the principal that a boy hit my boy and they expelled that boy

Question:

Hi,

I feel so bad about myself because my boy's friend hit my boy. I spoke with the principal and I told him that not every school has the program that he needs. My son's friend has problems but the school doesn't help. I felt like I did bad, saying what I said. I never said he needs to leave the school, I said that not every school has a program for each kid.

Please help.
