I disagree. I think right now is when you absolutely need company. Even just someone to go to coffee or get a breakfast with. The problem is that when we are overwhelmed with stress, our impulse is to isolate. I've learned through therapy a technique called "Doing the opposing action," when under any strong and negative emotion. So with grief, despair, or sadness - we want to isolate and that needs to be a signal to reach out. With healthy shame, i.e., you did something unhealthy but you're still not a bad person, we want to hide, but the best thing to do is to fess up to the person/institution harmed, and try to make it right unless the other party says there is no need.
It's the same damn thing for me with my substance abuse recovery meetings. When I'm thinking about relapsing or trying out some new addictive behavior, I do not feel like heading into a meeting. I've learned to recognize this signal, again through counseling, and when I do get to a meeting when it's the last place I want to be, then I invariably come away feeling quite relieved and glad I did get some contact with others who understand. This is the same if I didn't even talk during the "sharing" portion of the meeting, and if I do share, I'm not obligated to discuss the immediate temptation.
I'm loathe to dispense advice because I have no idea what's going on aside from letters on a glowing screen. However, in this case (and also in immediately prior post re: outdoors safety), I'm talking about things that apply to any single human being except a very young one. In this way I do not need to have a whole picture, because all I need to know is that you are affected by the human condition.
