Glad you had words. You'll run yourself ragged, which won't do anyone any good
I do hope you are doing OK. I take tablets for anxiety and would be lost without them, especially at this time. What you mentioned about feeling cold sounds like anxiety to me, which is understandable. It feels like coldness/fear running through your arms, yes? I hate that. Very disconcerting.
Berks is doing well thanks. Full of beans. Getting used to being hand fed. We have to crank his mouth open and put the food to the back of his tongue and he swallows it whole. Because he can't use his tongue and it is folded back, if he tries to eat he just gets it stuck in his mouth. I have found all sorts in there, lol. Drinking - I have ordered him a pet water fountain this morning, hoping he can learn to take a drink without always having to ask us. I know he likes to be self sufficient 
He is also enjoying his midnight snacks. Last night it was ham and cheese. Well, why not.
He's started his reduced steroid dose now, which is better. Murphy has done that too, yes?
I am beginning to think (hope) we'll have Berks with us for Xmas too. Not sure what to get him but he loves opening pressies so maybe treats wrapped up. He has everything else a dog could wish for and is so hard to buy for in his old age. Yeah, let's think positive and get them pressies, hey
I am even daring to hope he'll make his 16th birthday in Feb but we shall see.
Next check up Thur. Those always make me anxious. I'll be waiting to hear how Murphy is doing too and cheering you both on.
Hugs and woofs to you both xxxx
PS I started Berkeley on CV247. I am not saying it is a miracle cure or anything and it may be a right load of old hocus pocus but I spoke to the vet and she said it can't hurt. I just want to like to feel I am doing everything I can. He took it 3 years ago for a tumour, also on his tongue. I always say you just never know.
