Sleep aids

I lost my son 3.5 months ago. I haven't been sleeping well at all. Border line insomnia at this point. I sleep maybe 3 or 4 hours and not even straight. I toss and turn and wake up the whole time I actually sleep. I'm not big on meds. I've been trying natural with no luck. I've tried a ton of different essential oils, melatonin, warm showers/baths, and CBD oil. Any other natural recommendations? I'm getting to a point where I'm gonna have to see my dr
