BAD constipation... PLEASE help!

Hi everyone, I thought maybe someone could help me figure this one out. I am very constipated, on average I go once every 2 weeks but even when I do, I don't have full bm and they are usually undigested ( dissosicate easy in the water. I can not for the life of me figure out what is going on. I don't eat gluten, dairy, eggs, soy, corn, tomatoes... I eat whole foods and have a healthy balance of cooked vegetables, animal protein and grains. I have tried raw food for 3 months and it only made it worse. This is something that I'm struggling with for the first time in my life and has caused a tragedy in my health as nothing is being absorbed/excreted. PLEASE tell me what I can do... I am a 29 year old female who has recently experience adrenal fatigue. All hormones are in normal range.
PLEASE help
