It is always sad to hear that a young person has lost their life. My youngest son is just a year younger than Joe was, and I have no trouble imaging similar pain. But imagining is nothing like actually experiencing it. And I lost my father to cancer three years ago, so the stresses of your mothers death are obvious to me. My heart goes out to you and yours.
I thought I should say that before I say welcome. Because you indeed are, but that seemed secondary to acknowledging your grief.
If you wanted to be dependent on us for psychological recovery, you'd be in big trouble. But if you are here for the camaraderie and a little fun, a little angry gnashing of teeth and a little blowing off of steam, then you're in the right place. You will have to be tolerant of certain major flaws. At least in me. But if you can handle that, you'll enjoy it here.
