Colorful Sharpies and/or pens would be nice. Maybe a small notebook to jot down and organize thoughts may be appropriate as well. Every store environment is different, but most would appreciate unexpected gestures like gifts. It is kind of you to have your co-workers in mind. Here's hoping your positive energy is returned threefold.

That would be so kind honestly!! Though just be sure to be in the know of any partners allergies/ candy preferences (since ik theyre usually included in goodie bags 😤) it's so nice to know when your ssv's care about you :) I brought in cupcakes once and my coworkers seems to really like it

Tbh as someone with lots of mental health stuff Id be annoyed getting a goodie bag for mental health day instead of just nothing, sorry. Thanks for thinking of it tho <3
