I don't want to delete Snapchat, but maybe I should?

I'm on day 40 no PMO but I may have been edging this entire time on accident. I've never really had a problem with traditional internet porn, but I did fap to girls that would send me naked snapchats and talk dirty to me through snapchat A LOT. Through my streak, I have regularly snapchatted with girls, but very limited in sexual talk (every once in a while it would be brought up). I am still dealing with brain fog issues and a general "gray-ness" that has been my main concern this entire time. I didn't start nofap for any porn or masturbation addiction issues, but rather physiological health regarding my brain. My question to the experience nofappers is do you think I need to delete snapchat altogether for a successful reboot? Though I am not sexual in my conversations, the simple act of using snapchat may be a p-sub trigger in my brain. I should also mention that I am incredibly lonely because I have no friends in my current city, I work full time as a teacher, and I am taking a maximum course load of graduate credits. Snapchat has become my main method of communicating with friends and I really don't want to delete it and have no one to talk to, ever. Do you think that deleting it during weekdays but allowing myself to use it on the weekends would suffice?
