I'm liking your post not because I like the way you are feeling ( far from it !) but because you can admit to feeling that way . It's entirely normal, and TBH I get more concerned when I hear of someone being overly blasé and upbeat about it at this stage, because all too often it hits later, and harder .
I don't know if this helps, but acknowledging how you are feeling and allowing yourself to grieve , get angry about it tends to be healing and lead to if not acceptance, but coping. Yes, it IS royal pain in the ass at times, yes, your life is different and no, we have no choice but to get on with it but also can find out tips and tricks that work for us to make it that wee bit easier. But certainly for now be gentle with yourself, you are half way through the hardest part. The first year. And you are doing **** well !
