I think a change of scene can work wonders. My DD was diagnosed with anxiety and depression during her sophomore year. (She had anxiety in HS, but it was manageable). She tried a 3 week Spain program summer after sophomore year, and it didn’t work out. She came home early, found a new therapist, found a medicine that worked, and went to Ireland for second semester junior year. She occasionally skyped with the therapist. It was a fantastic experience for her.
I think a lot of her depression was related to issues with people at her smallish college, but she went on a program for her college, and spent time in Ireland with people from her college - in addition to some new Irish friends and students from other American universities.
We were pretty sure the Spain thing wouldn’t work, because it was right after sophomore year and she was in bad shape. Unfortunately, we didn’t know how she would be feeling until it was sort of too late to cancel - so she decided to give it a try.
Ireland worked out better than we hoped for. We were worried, so my husband and I planned separate trips - turned out not to be necessary. (She also got a visit from a cousin)
My younger daughter also has anxiety, and is planning to go away fall of junior year. She was first thinking about Australia, but is now focused on England. I am really glad she changed her plan. A 6 hour flight to/from Europe (from the East Coast) is really doable. I would have been extra worried if she were in Australia.
In both daughters’ cases, we thought we needed to defer to their choices and there feeling about what they could handle (with input from counselors)
