Give it time - you are actually doing very well.
I think the problem is that you were not prepared for a prolonged convalescence and are having to get your head round it. Get in some good books, start a craft project - anything to make this down time constructive. It has taken me 7 months to surface from my surgery and the problems that surrounded it, and reading, quilting, making banners for a folk festival, writing poetry, listening to music and much else has occupied my time constructively and I have felt that, although I have been unwell and under par, I have at least used the time in ways that have enhanced my life and others'.
I have also been working at training myself to play the piano without repeatedly looking down at the keys - I can only manage that in shot bursts!
Start small with some good books and work up; but above all else rethink this as I time that you can value and not as a waste of time!
At one point, getting out of bed or having a shower were high points for me!! A visit to the doc's would have been way out of my league! - so you are doing well.
