I don't have any suggestions, but just my sympathies. I wasn't a HG kid (IQ about 130 back in the 1970s) but was gifted enough to get through most of my schooling without effort. I *still* have a hard time dealing with frustration. (In fact, I was just fantasizing about quitting my job the other day because I can't figure something out that I think is really important.)
That all being said--I *did* eventually figure it out, once I got a 2.0 GPA my first year in college and totally freaked out. I'm still not amazing at dealing with frustration, but I can do it when I need to. And, I can make myself work when it's required, though I do still procrastinate. And, I'm pretty successful in my chosen field, well-liked by my colleagues, respected by my boss, good at what I do. (AND--beyond all that, I'm really happy with my life--my work, my family, my home... which really, isn't that what we want for our kids?)
