You don't have to be the one to try to deal with that - far less be expected to put up with it - can you write to your father's GP or practice manager and request help from them? There is help available, but if they don't know that it is needed it can't be offered. You are grieving too so perhaps you might contact your own GP to see if they can help you cope with what is now a double blow as you have, in effect lost both parents even though one is still alive.Thank you Grannylorraine. You could well be right but all I've done to try to help him. I lost my Mum in the summer and now my Dad is lashing out at me and I don't know what to do, I haven't got the strength for it anymore.
Reasonable thing to do. You need to look after yourself, and you've got your own grief.For my own sanity I'm going to need to give Dad space and leave Dad to contact me, if he chooses to do so.
