Hi Superheroine,
I'm so sorry for your loss
You clearly cared about/loved him a lot, and while this may not help much at all...........try to take some comfort from the fact that you were there when he needed you most, and you gave him loving care right up to the end, you did everything you could for him
Try to find some solace in the times you spent with him, the relationship you had with him, the fact you had him in your life..........and try to give yourself some of that kindness you clearly gave to him..........you
so deserve that with everything you're going through
