Tony sometimes seems very "wound up." at those times, he seems full of energy, talks very rapidly, and makes very grandiose plans. (one time, he gave away all of his belongings and was planning to move to washington, d. c., so he could advise the president.) at these times, he also seems to need almost no sleep. during other periods of time tony seems very "down." during these times he does not take care of himself. he seems to want to sleep all the time, and he often makes thinly veiled references to wanting to commit suicide.

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.
