Some meds can take up to 6 weeks to help but I think it depends on the dosage and the individual taking it. And it is okay to freak out about something as big as this. And then you will do what you need to do - get him the best help possible and support him the whole way. Let him know that it is not his fault and you don't love him any less. That you will deal with it together. That with a lot of patience and hard work, he can be happy and "normal", whatever that is. You've done this before so, as difficult as it is, you know you can handle it. Just don't forget the support for you,too. Freak out here anytime. We are listening. Good luck with your son.
