Sending you support also! My 4yo DD wears hearing aids for her moderate to severe loss, and is mainstreamed in a Montessori preschool, where she is doing fine. I remember how hard those early days were in the beginning. It does get easier. And I used to have "Denial Days" when I would tell myself I just wasn't going to think about my DD's hearing loss, because it was too hard that day. And sometimes those feelings come back, but they are brief now.
Do connect with an Early Intervention program. It really helps to be around other families and kids with hearing aids...that's the most reassuring to me, to see a kid in real life who is wearing hearing aids and acting like a regular kid.
