Perhaps to break down issues and solutions:
Radicalised sexism and other outwards blaming others: needs de-radicalisation therapy and a treatment of the underlying predispositions that led to being vulnerable to such indoctrination
Entitlement: personal therapy work to remove such narcissism
Mental health issues like depression, body dysmorphia, self-hatred etc arising from bullying, isolation, loneliness etc: therapy and medical intervention to treat those issues, plus treatment of the underlying issue that led to such trauma and issues
Physical unattractiveness: some can be treated with plastic surgery, gym and diet, better dress sense; others can't really be helped with current technology
Chronic loneliness: seems largely untreatable at present
Lack of charismatic attractiveness: therapy and education for basic stuff; things like neurodiversity cannot be changed at present
Inability to form romantic relationships because of unattractiveness: treat the underlying causes of unattractiveness where they can be treated
