GSUSA has some great mental health resources right now:
(1) Resilient. Ready. Strong. patch activities (you do not need to be a Girl Scout to do the activities; you also do not need to earn the patch)
(2) Taking Charge of Your Well-Being "Campfire Chat" (for Adults)
(3) Mental Wellness and Inclusion resources and activities for girls and adults; includes links to the "Raising Awesome Girls" blog and information about Mental Health First Aid for Youth
If your DD is not already seeing a therapist or leaning on resources through her school, I know it's late in the year, but it's worth exploring options for next school year to ensure she's supported there as well as at home.
