Am I screwed?? Can I fix this

I don’t even know where to start. Im shocked and kinda sad. I am having a ton of bloating, nausea, abdominal pain and feeling of fullness. My doctor is pretty much useless in helping me fix this. I’m open to suggestions. I can handle the brutal honest truth 😩 I was on antibiotics in October and will have to do another round of antibiotics next week. I’m sure it’ll make everything worse
