I am concerned about my son. His father had schizo affective disorder and committed suicide last year. Before this happened my son aged 28 was diagnosed with anxiety disorder. He is unable to hold down a job, disorganised and erratic. He is supposed to take medication but again he might take one day and not the next. He has also been quite nasty to me recently via constant text messages. I am worried there is a more deep rooted problem. However he refuses to get a formal diagnosis. His life is going nowhere and constantly blames me for bad advice even though i have always tried to advise on a practical level. Just very worried and problem been going on since he left university around 4 years ago.
