Sorry you're suffering. When medication makes a big difference, this means you need it to be stable. In this instance, its the same as being a diabetic who can't be healthy without their insulin.

My deceased brother had Bipolar and he was dysfunctional without his meds. If someone can do well without meds that fine for them but its also fine it a person functions better with them. You're fortunate to have a supportive family and I hope you feel better soon.
