2 year old starting preschool & im a wreck

Help me feel better about my son starting school. He's been recommended to go early because of a speech delay, poor comprehension and poor social skills (which is expected because of his background with birth mother) I'm sending him and acting excited and all that stuff but inside I'm terrified of him being mistreated and not being able to tell anyone. I'm scared he'll be scared. I'm a nervous wreck over it and everyone irl is making me feel like shit over it. No one seems to understand I'm not saying I don't want to send him I'm just worried about him. When I voiced these fears I get told I'm being selfish and trying to keep him a baby.I know he needs to go. He's been in speech therapy and he's been in play groups. But he needs this. I'm just worried because I can't be there and he doesn't have good understanding of things and what if he thinks I'm sending him away? Ugh it's just so stressful.
