Type 6 Stool Bristol Chart lately....Help please

Good morning, last couple days been having some issues with IBS. Once I have breakfast in morning with a cup of black coffee no sugar it helps me go to the WC, Last couple days been having like gases and urges me to go one again and I discovered stool Type 6 Bristol scale. Not black, no blood either, but, it scares the hell out of me since I am diagnosed with PTSD and Anxiety and Hipocondriac so I am thinking this could easily be Colon Can***. This makes me go into a panic attack. I would appreciate some tips suggestions. I´ve had a Colonoscopy done back in 2013 with 2 biopsis. Also I am intolerant to Lactose. i am living in constantly fear and it´s driving me insane...feel tired exhausted in my mind.
