Ambien/Zolpidem increasing sadness and anxiety? : insomnia

I’ll obviously talk to my prescriber about this but I’m curious about others’ experience with Ambien/Zolpidem. I’ve been taking the extended release Zolpidem 12.5 mg for 4 nights in combination with some other stuff I’ve been prescribed for sleep. Anyway for the last 4 nights I’ve probably slept the best I have in months. I’ve been so desperate to get this amount of sleep for months. However, I’ve found my already existing moderate anxiety has worsened and I’ve been increasingly sad. It’s not my first time taking zolpidem, I tried it a handful of times a month ago but didn’t have much success with it by itself. In hindsight I believe I struggled with sadness on those days too. Just wondering if others felt more sad after starting Zolpidem. Any feedback is appreciated! Thank you!
