I had to wait a few months for surgery, and wish that I hadn't, all I did was get weaker as I waited. My recovery was complicated by sepsis, but I was truly messed up inside. So it took me months to recover from my first resection.
I will say this much, the best to can do is let the Grad co-ordinator know what your facing, much of it unknown, and find out how you and they can be flexible with your program so you can do both.
There is no either or here, but there is a need for you to learn patience. Your smart enough for grad school, be smart about this too, for the sake of your health.
One note, I would not recommend going back to nuts, seeds, peels and skins ( you can peel and seed a good summer tomato, just don't refridgerate it. You can peel the seeds of ripe strawberries, I do it all the time.
I would also suggest you avoid raw veg and watermelon and apples raw, but other fruits and veg should be ok, cooked veg more better -- oo exceptions carrots and corn (they are near impossible to break down).
The thing is, you won't see the damage right away, so care is necessary.
This is not to say you don't treat yourself to things once you are really recovered. I went from my first surgery to a pouch, and that allowed me to eat much without worry cuz if it didn't break down, it got out of me really fast. Not the same though for a resection. Some days I miss that pouch... sigh....
Impulsiveness and CD can be a tricky combination, so please take care. And see what your Grad coordinator can help you with.
Facing surgery it is always a good idea to rally your forces, friends, family, teachers, employers.
I think you can get all that you are working for, but you might not be able to control the timing, and that's ok if you respect this.
