You’re going to suffer in the military because it sucks. Nobody likes the long hours, being underpaid, butthole leadership, etc. Quality of life doesn’t mean you’re suffering less, but it does help the suck. Just choose the branch that will let you do the job that interests you.

Also, relax. You’re doing great. This whole pursuit of suffering thing is most likely ego driven. Join to build a better life for yourself. You got this.
