ocd! help!

HI,


recently our 21 yr. old son had been diagnosed with OCD. He does have reoccuring negative, fearful, thoughts, which drive him MAD! This is awful. He is depressed as well. He tries so hard not to think these thoughts, but to no avail, and it's breaking my heart! I don't know what to do for him, there has to be a NATURAL thing, a natural herb, or whatever to heal this, or at least, control this! I know they said something about a seratonin re-uptake inhibitor? they want to give him something like ....clomipramine, or sertaline ... now, i don't want to do that! I would rather, if i can, give him something natural to deal with this. I do have melatonin here, and I don't know if that would help that much, he took one tablet (5mg.) the other day, and it SORT OF helped, but not to much. I was thinking, Seratonin? but how do i get that, and where? and how much would he need? The anxiety level is through the roof!!!!! He is trying so hard not to think these bad, negative, fearful thoughts, but to no avail. This is so horrible to watch!

If there is anything i can do...PLEASE post it !!!! thank you!
