You know what....it's okay to not feel okay (seems to be one of my favourite quotes at the moment). You've been thru so much and it's a shitty experience.
I did read something that made me remember how the little things can be important...it was about a lady going for a Butt Naked skinny dip and gave me a good laugh - she was really in the moment (and loved it)....
"What I have learnt from our impulsive childish moment was to seek out little magical moments every day (not necessarily as extreme as skinny dipping) but to allow myself to just experience 'spur of the moment' kind of joy, where I can create something special, to help me cope and realise that there is still much to live for and enjoy. I think I might have missed many such moments this past year because I got too caught up in my circumstances and felt trapped in my 'bubble' called cancer!"
Sometimes easier said than done and, maybe, if you can find one thing, regardless of how big or small everyday??? I have been known to smash plates sometimes (it helped me).
