this is excellent advice , a short course of diazepam to calm you down and get a plan of action for the next few days
If you are suffering from depression and anxiety a decent gp will just give you diazepam for a couple of days then try some counselling and , or , anti depressants
Its so important you act now , not tomorrow , now
You will gain a sense of control
Dementia is an awful illness to witness but there are people out there who can help your wife and you
