My "buddy" from the UK has been sick in and out of hospital...

Maybe once every couple weeks sometimes has to stay...

Its wiped him out financially, his insurance expired, hes heavily medicated and its hard to travel...

"Hes" 62 days over visa...

Scared and struggling, please advise on what will happen, no scare mongering please and please only give advise if you are sure ir almost certain its correct.

He wants to go to cambodia pay the fine and hopefully get back to Thailand in the near future.

Because "hes" unwell a detentiom center would probably make him extremely sick and could result in something catastrophic.

What should he do?

Thank you so much for any advice
