MaBBMom - I'm sorry to hear you had such a tough evening. Like has been said, it's very normal for us to worry about kids when they are facing and struggling with new challenges. Also, as has been said, I think it gets better.
Not only do I agree with TXMom that prayer is helpful to my soul, I think it can help our boys. I did remind my son last year during a trying period that he should also reflect and remember to say his prayers. I don't know if he's continued or not... I hope so.... but I believe highly in the power of prayer!
Thanks for sharing your feelings here because I can assure you there's another parent out there who's feeling the same worries and stress as you. You've just made her feel better as she's reminded she's not alone neither!
Keep us posted on your son's progress.
