They look able bodied to me and no mention of any mental health issues, although i guess that is probably the underlying cause. Get a full time job, or two part time ones, any job, even at minimum wage, work overtime, like 50 hours a week in total. And find a partner who does the same. A couple doing that should then be making almost 1000 euros a week after tax.. I guess strong worth ethic (conscientiousness) is a trait you are born with or not. But all that hard work can get ruined if you have mental health problems..
Living 3 in there. Prob lots of sex, a joint from time to time, no goals, - no vision. Just, living/existing. Must be mental. Besides, females are less more likely to compete in life anyways, thus, slightly mental plus no desire to crush it in life, brings such situation.
