Thanks so much for all of your support and responses.

Yes, my son is in therapy. I feel that this is a very slow process and have not seen results yet... I do realize it takes time, but when you have a child calling you multiple times a day telling you that he is feeling suicidal, progress seems impossibly slow. Please know that my son is very verbal and though he is free with his "thinking of suicide" I now feel that his "vocalizing his thoughts" and the low state of his mood does not equate an actual intent or plan to take "final steps." I think he calls and tells me becuase he knows I care and he feels to discuss his mood/outlook with me. Don't get me wrong, it is REALLY stressful but while I try to be there for him and help him re-focus, I feel that this emotional tanking has to level out somewhere... maybe when the Lexapro usage reaches the 6 week mark!

Again, thanks so much guys!
