No, I don't think that likely had anything, or very much to do with it... If or unless, you were horribly abusive, or something like that, with or on him. Then that might be a different story. As you know: there's the environmental side of things (of which, you are only one slice, or part of the equation) & then the genetic / component. So understand that - even if you did do something to him, which would allow or account for this. He has been an Adult now, for a little while anyway (even if not fully capable of being whatever that might entail; in terms of, 100% of this, or that--responsibility wise, or successful enterprise in life & such). . . And so, he too is to be held accountable for that which is in or under his control. If he's got diagnosable depression (levels of). And even more so, if he is not be treated (professionally). Then that is going to be a bit of a barrier, or a hindrance. To his cause, and his forward progress in life. So my whole point in all of this, is that, you are not to blame for however he turned out, with respect to his level or quality of depreesion that he is facing in his life. Flor there are mnay other factors. And also, it is a trying time in many peolpe's lives at this juncture or age, in which he is at. Maybe things will even or smooth out a little bit, onc e he turns tthe wcorner 9sort of~*) best wishes! Don't go too hard on yourself, and give yourself a break. I can tell you're a good/great/wonderful & terrriific Mom: just by the way in which oyu speak of him, and your otehr kids too.
