Now I'm not walking

dont panic im am walking but, I lost my beloved border collie a week firday,he was put to sleep.apart from being totally heart broken and crying till my head hurts,the knock on is im not doing my two hours of walking. And don't i no it.im sooo stiff sore and I can barely walk to the bathroom at night ,replacing him is easy said then done. The scary thing is I no just how bad I am not doing the walks .

I've heard exersize is good, but I've also noticed emotional pain, negative people, mean rude people, can trigger flare ups. So don't be to hard on yourself. Get well soon ok?
I'm back to bed due to being around way to much stress.
