Leaky Gut, Constipation and Gluten Free?

Chronic constipation since childhood.

Age 37: Started feeling toxic & inflamed like blood wasn't clean, sluggish digestive system.

Started seeing DO and Chinese Doctor at Fort Worth Wellness Center: weak guts and inflammation on kidneys, liver and lungs, bad circulation and imbalanced hormones.

CDSA result: SIBO, proteins not being digested, very low pancreatic enzymes, very low probiotics, some yeast overgrowth.

Doctors helped me tremendously:
Powerful herbs cleared up inflamed and toxic feelings, kidneys improved keeping salt in my system, digestion/constipation improved with adominal pumping, deep breathing, yoga exercises, only eating 3x a day, adding foods like rhubarb and cactus, avoiding stress and taking time to be easy and digest slow and relax after eating (I can't eat around stressful people or places)

I improved and was having daily bowel movement then bam went down with abnormal severe weakness. I was not tired and was sleeping well at night but so weak I could do nothing, not even walk more than across the house. Scary. Worst I felt was hard to describe but like my organs were fighting for strength and blood flow. Bowel movements stopped.
Infection of the gut caused by stress and leaky gut?????

PCP ordered blood tests, CT scan, 24 hr urine test and chest X-ray. All good results.

Gastroenterolgist ordered abdomen sonogram: normal.
EGD upper scope: Gastroparesis

I am strictly avoiding dairy, gluten, spicy food, alcohol, coffee, fruit juices, tap water. (still trying to understand gluten so avoiding all grains including oats until I figure out the rules) any help here?

Eating balanced diet of veggies, meat, beef bone broth, fish, white rice, fruits and only drinking purified water or coconut water.

Only doing passive yoga stretches, slow walks and resting until I get better. I used to be so active and hope to be able to run and bike and exercise again.

Digestion has improved slowly and I don't feel as scary weak but my body needs a lot of rest. I can only walk a short while and bowel movements have not been easy. I get urge to go but then it feels like my guts are so tight and weak they won't push out waste.

Any advice to heal gut?
