I haven’t been working at a small company for long and like to give my coworkers small gifts on holidays. It helps make the workplace friendly. Everyone is happy to get my gifts, but no one gives me...

A reciprocal gifting culture doesnt exist in the way you want. Youre coping with that reality.
It's hard when we engage in a behavior that makes us... feel not-valued. You could set that desire aside and think about what benefits you recieve from giving without expectations. Do you enjoy seeing recipients happy with your gift? If thats not enough - Are there other less -grand ways to appreciate them that would set THEM up for success ? Less cost to you, less (unknown?) pressure on them?
If you want to give AND recieve gifts think about why that is. It seems this is taking space in your mind and something unpleasant is surfacing -agitation? confusion? When that happens I try to step back and hold those emotions tenderly. When we give gracefully to appreciate the recipient it's a beautiful gesture. When we recieve gracefully we shouldnt feel pressure . Your gifts are a kindness you put out there. We dont always get gifts exchanged tit for tat. more
