Still no solution to my dysbiosis and leaky gut

So I have had this gut issue for nearly 2 years and I still haven't found a solution. The symptoms started 1 month after I experienced some trauma so I'm sure that was the cause, however I am 100% over that now and have been for over a year but my symptoms still remain.

Symptoms:

• Acne
• Food intolerances - Greasy/fatty food, nuts and some breads
• Low libido
• depression
• weight loss/impossible to gain muscle
• hair loss
• fatigue
• Trapped gas
• intestinal gurgling
• Loose stools
• Fast transit time
• abdominal discomfort
• Pale stools which sometimes float

• Background tests:

• colonoscopy - nothing found

• blood test - liver healthy, no deficiencies, not celiac, no blood in stool

• parasite test - nothing found

• fecal calprotectin - raised at times but most recent test was normal

• fecal elastase - normal

• Ultrasound of abdomen - normal

• 2 SIBO tests - negative

• comprehensive stool test - High levels of dysbiosis and leaky gut

what I have tried:

Blend of herbal supplements and low sugar diet/no processed foods - Nothing worked

Eating lots of fermented foods - after 2 weeks gave me extreme abdominal discomfort

Low fodmap and anti candida diet alongside oil of oregano for 6 weeks. At one point after 4 weeks stool improved significantly - texture and colour returned to normal for a week however after that it just went back to its normal fluffy, floating, pale (yellow/golden), loose state.

I have just started trying S boulardii, bacillus subtilis and postbiotics. Is there any other probiotics or supplements which you think can fix my dysbiosis and leaky gut?
