It's hard not to talk about it though sweetheart when that is all that is going around in your head at the moment though isn't it?
The pain of the loss of a partner of 30 years, and the worry for your future is overwhelming, it consumes you, day and night, the stress makes it difficult to eat, sleep and function normally, I know, because I've been through it.
But you will get through it, you have no other option anyway, unless he decides to come back, and I sincerely hope you wouldn't let him do that.
It will get easier, but it does take time, and I realise that's the hardest part, waiting to feel "normal" again. It is a new "normal" though, and you have to recognise that. Sending you love and strength, xx
