I too have Crohn's Disease. June will be 10 years since my diagnosis. I haven't had any surgeries, but I have had many flare ups. I'm on medication now and it seems to be doing really well.
As far as the best places to live, it sounds like you've been a "city mouse" all your life
Have you ever considered moving to the country?? I'm from North Carolina but I lived in Baltimore, Maryland for about 14 years, which is where I was first diagnosed.
I was young then and still wanted to be wild so i didn't take the time to take care of myself and understand my condition. I still wanted to run wild.
Fast-forward to the present, I moved back home to North Carolina last year (February 1 will be a year
and I have to tell you, I have never gotten so much rest!!!
The pace is much slower in "country areas". Not so much hustle and bustle and feeling the need to keep up, which is usually the cause of alot of stress.
If you have any Family/Friends who live in rural areas, check them out! Spend some time there if you've never done so and really pay attention to the affect it can have on you.
I hope this helps! Take Care
