Okay, here is what I think. First we start with what is: "avpd ...patterns cannot fully be cured or treated." So it will not be overcome. Rather, what is likely possible then is that you may find a way to be in relationship with avpd that is less stressful. I read the question then to be:
"Will I find a way to be with avpd that is less stressful?"
You are Jup and the disorder is the 6th, ruled by Sun. With Sun in the 4th the chart is descriptive, the 4th symbolizing being deeply rooted as you describe avpd is.
Sun and Jup are in favorable mutual reception, by exaltation. And Sun applies to aspect Jupiter. It is by square, so it is challenging; it will not be easy. But you know that already.
I also think that mutual reception by exaltation may suggest that there is benefit to your effort with the disorder. The benefit will be greater in the beginning and then fall off pretty quickly, as is the symbolism of exaltation.
Moon, as your significator, is in Taurus, which is favorable. When Moon is exalted, a symbolic interpretation is that your feelings are put on a pedestal, that their importance may be overemphasized. This is not to say that your feelings aren't important; it is to say it is enough that you are avoidant, that you live life through the avoidant lens. You don't have to feel bad about it on top of the difficulty of the avoidance itself. That is, if the avoidance is like being shot by an arrow, feeling bad about it is like being shot by a second arrow. The first arrow is enough, and it is one we may not be able to do anything about. We can do something about the second arrow, your feelings about it, by cultivating a different relationship with the disorder.
Moon's next aspect is a square to dignified Saturn. I think this points to there being obstacles to your establishing a different relationship to the disorder, perhaps based on your preconceptions about what you can do or forgetting that what you may do is primarily to become more at ease with how things actually are, more at ease with being avoidant.
