I recently shared a post in a local mental health professional group about a brief educational Zoom session I’m hosting on treatment-resistant depression, including general discussion of where options like TMS and esketamine may fit.

This session is intended for mental health professionals and referring providers and is not designed for patients or family members seeking treatment advice.

If you are a provider and would like to join the professional group or receive the Zoom registration link, please send us a direct message, and we’re happy to share more information.

This chapter is about the quiet part of starting over.

No applause.
No shortcuts.
Just showing up when life feels heavy.

I just released Chapter Two: Starting Over, a short cinematic film inspired by a true story.

Dr. Nigam explains the science behind Spravato in our newest video. It works fast (sometimes within hours to days!) and helps rewire the brain's connections. ⚡️

Did you know there’s a nasal spray FDA-approved for depression that doesn't respond to standard pills? 🤔

Check out the video to see if this might be the missing piece in your mental health journey. 👇

Chase the Light ☀️ Light therapy is one of the most effective treatments for SAD. Sitting in front of a specialized "light box" (10,000 lux) for 20–30 minutes typically within the first hour of waking up can mimic natural sunlight and trigger chemical changes in the brain that lift your mood.

Tip: Even on cloudy days, try to get outside for a 10-minute walk before noon.Feeling the "Winter Blues" or something more? ❄️💙 Body: As the days get shorter, it’s normal to feel a little slower. But if you’re feeling weighed down, hopeless, or just want to hibernate until April, it might be Seasonal Affective Disorder (SAD). We wrote a new blog on how to spot the signs and 5 simple things you can do today to feel better.

When words aren't enough, art can speak. 🎨✨

We are thrilled to introduce Emily Hinderliter, LCPC, ATR, to the Southern Illinois Associates team!

Emily isn't just a skilled counselor; she is also a Registered Art Therapist. She understands that for many adults, explaining trauma, anxiety, or depression in words can be incredibly difficult.

Through her unique approach, she helps patients:

Process complex emotions without the pressure to "explain" everything perfectly.

Reduce stress through creative expression.

Find new perspectives on old problems.

You don't need to be an "artist" to benefit—you just need to be open to healing.

👋 Say hello to Emily! She is in our Walkin Clinic (Adults 18+) at our Maryville clinic.

📞 Call (618) 288-5019 to schedule an appointment with Emily today.
