Your not alone ,my mum went through this with my brother , support him as much as you can and fight to get him help from the professionals, your not a failure , my son was Sectioned but he has schizophrenia, with medication, anti pscotics your son should hopefully get better soon ,it takes a while but be patient and he is in a safe place getting help but fight to get him help when he comes home , just give him love and support and also show yourself some love , it’s not your fault you’ve not failed him, your still there your still being his mum x
