Dealing with resentment in a positive way - if that's at all possible
No, IMO it isn't! Resentment, when it concerns disability and illness, is a feeling that we've been cheated out of something we should have, or were expecting to have. It's not untrue either. Things have not turned out as expected and there is no clear path or end in view. There's a long journey into the unknown, with little or no preparation before we set out.
Staying positive, or finding a way to feel more positive, can only come when you allow yourself to say
"It isn't fair, I didn't ask for this, I deserve to be in control of my life". That's not whingeing, it's acknowledging that
you matter. If you are honest about your own feelings you can slowly start to ask
"Now what? If there's no going back to what was, or what might have been, how can I accept a different plan for my life than the one I thought I was going to get?"
There's no avoiding the fact that uncertainty is stressful. TP is a safety valve for many people. Resentment and disappointment is often expressed by posters as 'having a rant', or 'feeling sad today', or 'feeling so alone'. Whatever you need to post about how you are feeling, someone will answer you and remind you that it's OK to have those feelings, and that you are not alone.
