Literally unable to stay awake unless I take my prescribed stimulant - does anyone else experience this?

I’ve been dealing with debilitating chronic fatigue. I slept in until midday today because I felt awful and needed the rest. I normally take my medications including my ADHD med around 8, so since it was much later, I opted to skip the ADHD med to hopefully not screw with my sleep schedule more.

It’s been damn near impossible to stay awake today. I’m semi-awake now but physically weak and it’s hard to speak because I’m slurring my words. This happens every time I forget to take my stimulant or choose not to for whatever reason.

Does anyone else experience this? In other words, being totally unable to function unless you’ve taken a stimulant? I hate being so reliant on a medication.
