Does the fact that a young man's life has not changed for the better after Hajj, but rather he feels that he has become worse than before, mean that his Hajj was not accepted? And must he avoid perfumes that he suspects contain alcohol, and avoid going to the hospital for fear of using alcohol-based sanitizers?

The acceptance of Hajj is a matter of the unseen, known only to Allah. Feeling dispirited after Hajj does not mean it was not accepted; rather, it should cause apprehension regarding it. Among the signs of an accepted Hajj are abandoning sins, replacing bad company with righteous company, and exchanging places of amusement for gatherings of remembrance. Other signs include an open heart, a luminous face, and Allah's granting the servant success in performing good deeds thereafter.

Regarding perfumes about which one suspects they contain alcohol, the original ruling for them is purity, and doubt is not taken into consideration. It is permissible to use them unless one is certain of the presence of alcohol. If one becomes certain of the presence of intoxicating alcohol, then it must be avoided in clothes designated for prayer because it is impure. However, it is permissible to use it outside of prayer, such as for sterilizing wounds out of necessity, or using something that has become impure in places other than a mosque, or in human food and drink.
