Tmi* & TW* Black stuff in mucus or bile?

I really hope this is ok to post here, and I know you all are not doctors and also, I talk to my doctor Tuesday so I will be bringing this up to her. I see a therapist regularly as well. So, please no harsh comments.

I’m doing a LOT better compared to a few months ago, but I’ve been struggling with bulimia for the last several years.

I finally got a handle on it and was doing very well until my spouse passed away and I fell back into a vicious cycle a year ago.

I’ve cut down tremendously on how many times I throw up compared to just a few months ago though. I started a new medication that has helped SO much. I maybe cave in once or twice a month if even that and have restored weight.

But I’ve noticed a few months ago, when I was doing it daily, that when I was done, I usually ended up with this blackish gray spots in the bile. One of the side effects of my medication is that my anxiety is about 7x worse, since I don’t have food to turn to. So I end up overthinking and panicking.

I guess I’m just looking for reassurance that this is most likely NOT lung cancer. (I am not a smoker but was around heavy second hand smoke for the first 18 years of my life. I’m now 26)

***its from my mouth. Although, it could be sinus drainage mixing in too? But I never noticed it until I was done, so I assume it’s maybe from my stomach I’m not 100% though
