those with depression, what helped you?

hi im not sure if this is against any rules but i triple checked just in case. i have a younger brother on the spectrum and hes been suffering with depression and anxiety, and its only gotten worse due to the current political situation in the US. i feel horrible bc idk how i can help him. hes tried therapy but he wanted to find someone that he can text rather than talk over call. i was wondering if anyone on the spectrum with depression/anxiety can give some advice that can help with their symptoms? thank you so much. ♡
