What to do to control IBS-D

I am 24 year old woman and I have kinda always had tummy issues even as a kid.

I had some stressful stuff ongoing happen a few weeks ago. I have had diarrhea, lack of appetite, gas, bloating and lack of sleep for about 3 weeks. My stools also just look weird. I am seeing large pieces of undigested food like carrots and peas.

My diarrhea is getting better however I am having 1 large soft but formed BM immediately upon waking up then for a few hours after I have to go 4 to 5 additional and it is very small amounts of soft stool. It is very sticky and frequently the TP is neon yellow after wiping. I thought it was fat so I have been eating a low fat diet the past few days and it is still ongoing. I am having frequent pressure like I need to go but then it is just gas.

I went to the doctor and did labs. CBC, CMP, A1C and a stool test. Everything was normal however I haven't gotten the stool results yet. Maybe the answer lies there? I have also done a gallbladder ultrasound and xray and nothing was abnormal in those either. This is so strange because I am in zero pain. I just don't feel well in general.
