Hi, coping_father, welcome to PsychCentral (PC).
Situations should not stay frustrating. If we feel frustrated we should take a step back and see what is standing in our own way (are we trying to "control" someone else and how they feel or act? Are we unclear on our own agenda, what we want and our plans to get it for ourselves? Are we too near-sighted, not seeing the whole picture (children grow up and become adults and have to learn to manage with less help from we, their parents)) and revisit our plans and priorities. If we feel "stuck", that's a chance for depression to enter, if we do not confront the problem; facing a problem is not the same as banging our heads against it
