Life disaster or life experience

In November 2015, I developed an acute transient mental disorder and was admitted to the hospital for treatment. I stayed for a month and experienced the hospital life of a real mental illness. Regular, but also dull. The pleasant time every day is to smoke and drink Coke on the balcony. It would be perfect if it was iced cola. After leaving the hospital, it basically took two years to gradually return to a normal state. I also suffer from depression and insomnia. Of course, I didn't say that I was mentally ill to outsiders, but that I was depressed. The doctor is also very open, and the suggestion he gave me was to join their overseas travel group. But I choose to go on my own and take it easy. I am worried that it is very challenging to organize a group tour with a group of people with mental problems, so I dare not.
