What has your doctor said about your low blood count, b12 and folte? have you had your test for celiac?
IMO I would ask your doctor to check your bone marrow----low red blood cells could be indicative of a disfuntion in your blood making marrow---I say COULD. I am not a doctor , so please just go over this with him.
Please if you would keep us posted on this.
All the best,
