@Walter1407, I was fortunate enough a couple of months ago to attend a viewing of the Australian documentary 'The Unlikely Pilgrims' which took the tagline 'nothing heals like a little distance''. Its blurb states:
The film follows Ronan, a counsellor, who believes that rescuing can do a lot of damage. He also believes in the healing power of long-distance trails. Ronan invites a group of recovering addicts to walk the 800km
Camino de Santiago, with him as their guide. The walk challenges them to breaking point, and there is immense growth, but there is significant cost to Ronan as a result.
For me, it reinforced that anyone who encourages someone who is mentally fragile to join them on a venture like this takes on an enormous responsibility. Amongst other things, it really requires the person who acts as a guide to determine what is most important - the achievement of any personal pilgrimage objectives or the welfare and care of their companions.
