I'm not ready yet

The thing is, I'm really too young to have a son graduating from college in 3 weeks. I mean I just finished myself didn't I? Class of '82. I don't know why it is that even though I feel it happening, I am aware of the passing days, in fact they sometimes seem interminably long, but yet the years I can't see. My mother must have been terrified when in one fell swoop I finished school and got married and moved hundreds of miles away from "home". I admit that at 21 I never gave a thought to her point of view. And in fact it is only in the last year that she admitted to me how traumatized she was by her only daughter leaving home. Yeah, of course she was happy to "gain a son", but what choice did she have? I guess I'm dealing with it the way I deal with everything else unpleasant. I pretend to ignore it, put on a good face, and inside I obsess over it. (No wonder my body is falling apart...implosion) I wish him all the best, but I realize his life is really his own. I can give advice (even very good advice), but I can't make him follow it. And I guess I have to be ready to just support him wherever he goes. But I never realized how hard it would be to let go. (Okay so I never thought about it too much before...implosion here I come)
