I've been brainstorming "meantime" things since I first read, so here goes:
1. Distractions - find as many as you can. Fill up your life with things that you love (or at least love to hate) so that your mind is preoccupied. (I imagine there will still be an aching, but, unfortunately, I don't know how to fix that.)
You may think the whole "distractions" idea is childish, and it can be, but if you're anything like me, sometimes too much thinking can be a downward spiral. Distractions prevent that from happening, and they let you learn, try new things, help others, etc. at the same time.
I'm sure you have your own ideas, but just in case you need some inspiration these days, distraction examples may include the following: take an art/music/theatre class, learn a new language, join a social sports league, borrow our kayaks (we just got them and we LOVE them) and go out on the river with Kevin, have a picnic, go wine tasting, apple pick in the fall, go hiking or camping, start a huge home improvement project that requires oodles of research and planning and doing and redoing, learn a new recipe or cooking method, read lots of books (perhaps new genres or a classic you haven't read before) and/or reread some old ones, take up knitting/quilting/cross-
2. Shiny silver hope coins - take mine! I've got plenty to give :)
3. Keep going to church, praying, and journaling.
4. Nurture your relationship with Kevin. Do fun things together. Hold hands. Stay best friends. Find ways to help him though this journey, and don't be afraid to let him know how he can help you.
5. Keep eating well and exercising. See shiny silver hope coins. If mine happen to work, you want your body and mind to be in the best shape to grow your family. Plus, these are just good things to do anyway.
6. See your doctors as regularly advised and when issues come up. I imagine you and Kevin are doing this already, but I mention it because I have, in my "old" age, started to avoid doctors appointments. Don't be like me!
7. Find a couples or women's only support group. I imagine there are many, and I'm glad to help you find some you might like.
8. Make plans. If your situation or mental/physical health changes, change them. I can sometimes get hung up on the "oh, but what if X happens, and we have to reschedule/cancel? I will feel so [negative emotion] and our [friends, family, acquaintances] will be so [negative emotion]. Let's just say no now so we don't have that awkwardness later." Guess what? Plans change. And those who love you won't be [negative emotion] about it.
I'm not sure if this is what you are/were looking for, and I know some of these are trivial. But, at the very least, now you know that someone who loves you is reading your words and hearing your voice and thinking of you and wanting to help.
