unsure what to do ??

not sure what to do ????? My Husband has G.A.D , we have a small Mowing and Cleaning Business that we run, now and then everything builds up and we take a weekend off to relax but last week my husband took himself to hospital with an Major depressive Episode which they kept him in for a week , now we are back home with medication and awaiting mental health plan to get him back on his feet -- I have kidney disease stage 4 and can not drive ,so there is no income coming in -- today my husband said he feels like he doesn't and can`t work anymore -- the specialist said to ease back into work , any suggestions and advice will be great , just remembered the specialist gave my husband a Centrelink form -- 3 months sickness allowance to put in ?? but my husband is worried that we wont have any customers if we put the form in , at the end of 3 months but then today he doesn`t think he wants to work anymore Thank you
