Where can i find courses for personal growth with focus on to better myself and harden myself.

Thinking like military style or, physical training and mental growth, like getting pushed out of comfort zones.

I have a mental illness, like adhd and anxiety, and mild ptsd 

In my imagination, a place where you live for some time and getting pushed and sharpen up. 
.. There must be some place. 

I had a friend Who lived in a tempel in Thailand with monks for 3 months. Is not quit what im looking for but, it helps me think that there must be something. I know i might Cost, but I just need names or places. Google cant help me. 

Any place in the World is accepted.

Joining the military is not an option.
