Any advice

Hi everyone,
I’m a student and I’ve been living in absolute hell due to extremely loud, hyperactive gut noises and gurgling (Borborygmi) . It only seems to explode when I’m in the quietest settings, like lecture halls and exam rooms, which has caused me severe social anxiety. I even tried starving myself before classes, but it only made the echo and noises way worse!
I recently did some tests. Thankfully, my H. Pylori is negative, thyroid is normal, and CRP is fine, but I have low Ferritin, B12, and Vitamin D. My doctor suspects SIBO/SIFO is causing these trapped gases that collide with my gut motility.
I am currently on a 6-week structured protocol, adding something new each week. Here is my stack:
Week 1: Lactoferrin + Pepto-Bismol (Bismuth)
Week 2 (Current): Added Rifaximin
Week 3: Adding Ginger Root (as a prokinetic)
Weeks 4, 5, & 6:My doctor will introduce Saccharomyces boulardii, Zinc Carnosine, L-Glutamine, and Berberine.
My questions for you guys:

1. What was your SIBO type (Hydrogen, Methane, or Hydrogen Sulfide) and what were your main symptoms?
2. What was the protocol that actually worked for you?
3. Most importantly:Is there anyone here who suffered from these loud, embarrassing gut noises and managed to get rid of them completely?
4. I really need some hope and success stories right now because I'm terrified this won't work. Thank you so much!
