With his life as Don Draper securely stationed in the rearview mirror, Jon Hamm is enjoying the present and feeling hopeful about the future. That seems to be largely because he's put in so much self work that he known what his battles are in life and how to fight them.

His weapon of choice? Therapy.

In the new issue of Mr Porter's the Journal, the 45-year-old "Mad Men" alum speaks candidly about going to rehab for alcoholism as his booze-soaked hit show -- and his real-life, 18-year relationship with Jennifer Westfeldt -- were coming to an end.

He also admits he's headed to see therapy at the end of the interview, joking to the British reporter, "I know the English are a lot more skeptical about [therapy] than Americans are, but maybe after Brexit, you'll change your minds."

For Jon, here's nothing funny about therapy or rehab, though.

"It has all these connotations, but it's just an extended period of talking about yourself," he says of the 30-day program he checked himself into in Connecticut last year.

"People go for all sorts of reasons, not all of which are chemically related. But there's something to be said for pulling yourself out of the grind for a period of time and concentrating on recalibrating the system. And it works. It's great," he says.

There was plenty to recalibrate for the actor by early 2015, not the least of which was the attention that came with his career shift into one of the biggest stars in pop culture.

"It is not easy having immediate and huge-scale fame thrust upon you," he admits. "I'm a pretty shy person. I like talking to people one-on-one, but I do not like people taking pictures of me with 400mm lenses across the street. It's mystifying to me why we give that any time in our culture."

His newfound celeb status aside, Jon noted that he's struggled at other times in his life and turned to therapy for help. His mother died of cancer when he was young and as he tells the Journal, he was raised with the help of female friends of the family.

His father died when he was 20 -- and that's when things went off course.

"After I'd lost my dad, I had this horrible paralysing inertia - and no one in my family was capable of dealing with it. So what do you do? Go and see a professional," he says.

"I preach it from the mountaintops. I know it's a luxury and it's not something everyone can afford. But if you can, do it. It's like a mental gym."

With his mental state in tip-top shape, Jon, who declines to say whether he's in a relationship now, says he still enjoys living in his longtime Los Angeles neighborhood, Loz Feliz, although he's headed to see his aunt over the holidays. Asked if he dreams of starting a family himself someday, he admits it's not off the table.

"I don't think it's necessarily an imperative. I'm not going to psychoanalyse myself here, but… well, never say never," Jon says.

"I've got nieces and nephews and I've been a teacher. I've probably been around kids a lot more than all my friends. I feel if you shut that off entirely you calcify. You turn into that guy."

In the meantime, the Emmy winner is set to appear in at least five new films over the course of the next year. His latest, "Keeping Up With The Joneses," hits theaters Oct. 21.
