I have a theory, I have no idea how accurate it is.
Horses are considered symbols of power. The horse being power fits with "A force of nature filled with strength". I think that the "sugar horse, a friend in need" refers to antidepressants appearing to give the patient strength, but are really feeding off of them in ways, especially by clouding their mind (Her mind in a glaze, from the medicine gloom).
It could also be illegal drugs that someone is "self medicating" with to get through their days, sugar being cocaine, and horse being power, which would make sense if the "sugar horse, a friend in need" were the part of her craving it.
Both would fit, but I could be completely off. Personally, I think the first definition is more likely.
