Tuff, I definitely get that. I think a lot of us (all of us?) go through a grieving process when it comes to this illness, and that's not necessarily a process that stops. We grieve the life we thought we'd have but didn't. And we don't necessarily reach a point of acceptance and then stop grieving and that's that, because this illness is something that affects us every day and in pretty much every decision we make, every thing we eat, every activity we do, etc. It's ongoing. So I think the denial that you're in might be part of that grieving process. I get into denial sometimes too, particularly if I've had a few good days then I get cocky and into denial about having certain limitations when it comes to diet, I eat something I shouldn't, and let's just say that usually gets me out of denial really quickly!
I've read that when it comes to the grieving process and the stages of grief (denial, anger, bargaining, depression, acceptance), you don't necessarily do all the stages in order, you don't even necessarily do all the stages at all, or you might go back to one of the stages you've previously been in, etc. So, just because you're in denial now, that doesn't necessarily mean that you're stuck. It just means that you're grieving, and it's okay to grieve, because you're in a situation that sucks and has no way out and no end in sight. So, I'm no professional, but I've dealt with a lot of grief in my life myself, and what you've said sounds totally normal to me. Please allow yourself to grieve and feel your feelings, even if denial doesn't seem "right." And honestly, there's nothing wrong with looking into diets, treatments, etc. Wanting to improve your situation is also totally normal! It also sounds more hopeful to me than being about denial, honestly. They're always coming up with new and better treatments, and they may even someday come up with a cure, so it's perfectly reasonable to want to keep on top of that research. I think what you're doing, what you've described, it sounds totally normal to me. So please don't beat yourself up for being in denial. It's okay, I promise!
