How do i deal with my illnesses?

Prayer. I pray about it and have faith every single day that I will be healed completely one day, and that gets me by! I know that right now, I am suffering, but I also know it won't always be like this.
"The pain you have been dealing with now is nothing compared to the joy to come" Romans 8:18
I read this verse and it gives me a little extra boost of encouragement when I need it.
Besides prayer, the next best thing I can suggest in dealing with illness is to talk about it with someone. Whether you talk to friends, a psychiatrist, relatives, or you just write in your journal, it will help tremendously. Keeping things bottled up can be a large source of stomach pain for Chrons patients. Chrons is, after all, a stress-induced illness, so eliminating any unnecessary stress is advised if possible.
Try to engage in light exercise like walking or yoga, it helps as well, and that's what I try to do often.
Hopefully these things will helpful to others like they were for me!
