It all depends on how you deal with the stress,
there is meditation, yoga, etc... or if you have or think you have depression and anxiety, there are medications you can take but you should talk to a psychiatrist about it and make sure you check for any possible interactions between the psych meds and your chron's meds, (If you decide to seek that type of treatment)
In addition to the chron's and anemia, I have been taking medication for depression/adhd/anxiety and have asbergers syndrome. Ive been in treatment for the psych issues for 10 years.
