Boot Camp PTSD

If anyone who did the Boot Camp from any country (in my case Spain) will undertand this shit.

When they bring us 1 month of vacation and i came home, everything hits different, i make a better friendship with the people I met in barracks than my childhood friends and is fucking crazy. Like when I meet with them, is not the same, they talk each other and I just stay there looking around, boring as fuck. Is someone knows what i talking about or something...
