Alright, i'll try to make my feelings more clear.
Maybe solving one issue might not solve another, that's not what i'm trying to say exactly. What i'm trying to say is that they both stem from an original anxiety or insecurity somewhere. It feels like we're treating symptoms, and not the core of the problem. I don't claim to know what the core of the problem is, but i think there is one. I'm not saying solving her stage fright has to solve her self-confidence, i'm saying there's a deeper cause that all these issues stem from, and that we should be working on that level to get more done.
For example, lets assume the following:
1 causes A and B
A causes C, D, and E
B causes F, G, and H
