Charata is amazing! B”H you feel guilty. One of the funniest shaylos ive evet asked a Rav is how to do teshuva without feeling bad. Lol, now i feel guilty i used to be such an idiot.
I agree with chaya.esther, Mesillas Yisharim! Or really anything of that sort. I think instead of constantly telling yourself “i wont look at…” “I will stop…” “I wont…” You start by what you WILL do.
Your yetzer hara loves when you say i’ll stop blah cuz most probably you will fall once or twice and then he has a PARTAAAAY! Soo instead whenever you have this urge you say, “i will go and do blah but first i need to learn this whatever.” You have something good you ADD on rather than keep holding back. Like a baby, you cant just take away his toy you give him something to be distracted by….
Real example from my life, i wanted to watch a certain episode of something so i said i would but first i meed to listen to a whole shiur. By the time it was done i didnt have time vuz of HW and the likes.
We learn in Pirkei Avos “Mitzva gorreres mitzvah” one mitzvah leads to another. Stop yourself by just doing not stopping to do.
