Tuesday may have been the last time Bernie Sanders owned the limelight.
Surrounded by thousands of screaming fans, not unlike the rock-star reception he had faced many times over the past 14 months of his run, Sanders thunderously endorsed Hillary Clinton. He said he would do everything he could to help his former rival for the Democratic nomination win the presidency.
Sanders may continue to be a staple on the campaign trail into the fall. But as he tries to rally his younger supporters to Clinton's side, his departure from contention means he will likely experience some kind of emotional letdown.
Instead of being the focus of attention in large arenas, Sanders, 74, who was a relative unknown to most Americans before he announced his candidacy, will return to the town halls and school auditoriums that are the fixtures of being a U.S. senator from Vermont.
"There's naturally a withdrawal of some sort for everybody," said former Rep. Jack Kingston, R-Ga., who lost his own bid for the Senate after 22 years in the House. "That ability to influence what you think is important is greatly diminished and so you do have to come to grips with that."
Kingston added while there were negatives to leaving office and the campaign trail, it is not the end of the world for people with a sense of identity outside of the office.
"Your jokes seem to be funnier and your wisdom seems to be deeper," Kingston said of his time in office. "You're going to miss it, but I think that balanced people understand there's a time in life for things."
Psychologists agreed that Sanders will likely face emotional challenges in leaving the intensity and excitement of the trail, but they noted that circumstances are important and that it is impossible to know exactly how an individual may feel about the transition. But they said that in leaving the arenas and throngs of young supporters as he returns to campaigning in sleepy Vermont diners and his day job as a senator, something would surely be missed.
"It has to be heartbreaking to reach this point in his campaign, and I'm sure not just he himself feels this way," said John Grohol, a psychologist and founder of Psych Central. "His biggest loss is probably the loss of the idea that he would become president and being able to actually implement all of the policies that he has spoken so forcefully for."
The Sanders campaign did not respond to a CNBC request for comment.
