My Pdoc explained it this way. If he could lock people in euphoric hypo-mania's he would but because everything comes with a positive and a negative. If you take the high, which is super addictive, then you have to deal with the low or it wouldn't be fair to others. Not that he wont treat the low but kinda like it's a requirement.

I see it like this, look up Spoon theory, on your high's your throwing away as many spoons as possible stealing from other days. Then you crash, you have no spoons to do anything so you have to wait for them to return. Since you borrowed there's no way to return all of the ones you need for a day but meds and therapy can help you return a couple to cope while you wait for the rest. I don't know if I explained it well enough if not I'll try to explain it better.
