Katierose, I left medical school when I had moderate to severe depression, and it took me a long time to get my confidence back (it's not perfect now, but it's pretty good). I joined the red cross as a volunteer after 6 months, and I went from someone who looked down when I walked, to facing the world head on, learning how to deal with things. I started in the shop, within 3 months, they made me a keyholder so I'd open up, manage, count up, etc. Then they asked me to join their staff-volunteer council which keeps communication going between the 2, and then I became a schools volunteer, presenting/running workshops in schools about global issues. It was a huge confidence boost, as I would never have dreamed of doing any of those things before....presenting, being trusted with the shop, etc, etc. I can't recommend volunteering enough. Also the comraderie (sp?) is second to none. And the RedCross maintains certain values e.g. to be non-discriminatory, non-judgemental, etc. which made me feel better going there with depression (although I didn't tell them for a year). They also do lots of other things, like doing hair and make up for terminally ill people, alternative therapies for them too, skin camouflage for people with skin conditions who feel too apprehensive to go out, etc. Oh and they give fabulous references
You only need to go as much or as little as you want too.
It's just a suggestion, just in case she does decide to go for volunteer work.
