Should i wax, bleach, or thread my mustache?

alright so before i travel on saturday im planning to wax my mustache. im leaving for a full month and my mum says if i wax or thread it, it will come out in a week which means i gotta get with me a bleach set. ive been bleaching my mustache ever since but idk it still kinda shows and i dont like it at all. my friend waxes hers and is encouraging me to do so too. but she kinda gets alot of pimples on her upper lip and the hair kinda came out tiny but alot... so i dont know im just 13 i dont really feel comfortable threading...
