zig, the "friend of your friend" is having an MLC or her friend's H is?
If it's the friend's friend's H, then certainly sending her here (so long as YOU are comfortable with it, if she knows you are here) and also point her to research on MLC specifically...
If it's the friend's friend... then the only thing you can do is see if this person believes they might be MLC. If so, recommend they read up on MLC. There are a lot of online resources. Also she may want to seek a counsellor, specifically with that admission.
If it IS MLC, then the only way past it, is through it. Any reading resources might help a person at least understand. The introspection still needs to be done. Maybe MLC can be downgraded to a transition by someone who admits to it and accepts counselling. *shrug*
