im clean for just over 2 months, but im getting urges again

for a little backround, around 2-3 months ago things were really really bad so i was sh, and things were getting slightly better but recently my dad has been getting so much worse again and yelling at me, i just want all the hurt to stop again, but i dont want to sh again because 1. im going on holiday in like 2 weeks, and i dont want my parents to see. 2. my parents dont even know i did it the first time, and my scars are fully healed now so i dont want them to see anything

does anyone have any tips on how i can stop the urges or any alternatives i can use?
