Answer:
Tony is showing clear symptoms of bipolar disorder
Explanation:
Bipolar disorder used to be called manic-depression. A person with this disorder has its "ups and downs", in other words, polar opposite behaviors in a cyclic order. These swing in moods can last for a longer period of time, than what an unaffected person experiences.
When the person is experiencing the manic-side, or mania, they are usually as Tony showed in the first half of the script. They experience grandiosity and are up and about even with as little as 2 hours of sleep. After a few days to wekks, they go into deep depression, as seen again in the 2nd half of the narrative about Tony.
