Is it possible to tell your Primary Care about your depression and obtain a referral for a full evaluation and/or care?

How is your diet these days?
Is there a way to boost your nutrition without further aggravating your stomach?

You are aware of the SCD Lifestyle? Many report drastic GI improvements; yet, not everyone does as well as others.

Hopefully, with strategy and with time -- and lots of helpful input from members here as well as from your doctors -- you will be feeling better relatively soon.

I am sure others will be along with suggestions.
