<human>: Ive had this friend, lets call her Janet, for the better part of 5 years now. Shes been sort of a mother figure to me so im not inclined to use this knowledge against her. While working on fixing Janet's laptop I found picture and video evidence of her being a call girl and meth addict. Now this really doesn't surprise me, shes been on and off meth for decades now, but most of all im just concerned for her as this is a situation thats only developed in 2015. Shes a very sweet person and the last few years havent been kind to her, she lost her job as a successful business woman, her house and car, the majority of her family photos and heirlooms. Id march on hells gates with nothing but a water pistol for the handful of important people in my life and maybe thats just dumb, but I cant see her choices as rational, I can only see them as desperate. The advice Im requesting is just how to approach her with this knowlege. Now that im aware I can see the lies shes told me over the last year and its got my jimmies rustled a little. But Id love it if she quit the meth, and I have no idea how shes treated as a call girl so I cant say i really know if thats something i would try to stop her from doing. Ive breached her trust by looking through her private data so shes gonna be pissed if she finds out, but im concerned for her. I wouldnt have known how bad off she is if I hadnt looked. Me and her son are pretty tight, and im not going to let him know any of this right now, but I think we're probably the only 2 people who really care and worry about her. Saying peace and ditching her to avoid bullshit really isnt an option, or its a very last resort.

Could you distill the essence of the text into 1-3 sentences?
