I would love to see a Menières disease. It can have a big impact on your life. It is often combined with hearing loss and a bad case of tinnitus.

1: Misophonia, one of life's seemingly minor inconvenience that can actually cause so much stress and visceral anger. The paws could be sewn to the ears, as if to block sounds, maybe embroidery in red on the belly area to represent that visceral anguish and anger, linked to embroidery on the ears.
2: Misophobia, a bright white rabbit with a face mask, gloves, maybe the inside of the ears could in a pattern reassembling hospital gowns fabric.
3: Cataplexy, the plush could be less stuffed to represent the lack of muscle tonus (floppy plushie) , with closed eyes for the sleep disorder part, maybe in a dual color, dark and light, for the falling asleep during the day (light blue/dark grey maybe)

Maybe an IBS bunny? I would love to have something to cuddle while my stomach is acting up

1. Dementia plushie. My grandfather passed back in March this year. He was 96 years old. I saw him go through his dementia as it started when I was probably 12 or 13, and now I’m 25. It’s really hard to see your loved ones go through that, forgetting who you are, who they are, and so on. I’d love to see a dementia plushie and yalls take on it, especially since it is quite common in today’s day and age.

2. Addiction plushie. I know y’all have a SUD plush but I’d love to see another design. I personally am an addict in recovery. I was addicted to stimulants and kept on relapsing and then getting sober and so on. Today I am over 2 years sober and I’m very proud of myself but I also can’t forget what I’ve gone through. I’d like to see y'all incorporate the “One day at a time” saying that we say in NA. Maybe a calendar to keep track of time sober. Or even maybe separate plushies for alcoholism and drug addiction.

Other ideas:
Arthritis
Munchausen by proxy
Narcissistic personality disorder

I would love to see a sleep apnea bunny. Could have a cpap mask
