I wanna come out to my dad but I'm scared... What do I do?! I need a way to tell him I am this way... Without being scared of him rejecting me ...

Well, do you legitimately think he will reject you if you come out? Do you think it’s a safe environment? Has your dad shown signs of homophobia in the past? If these questions don’t sway you away then go for it, but please put first your safety before anything else and make sure you have something to fall back on in case it goes wrong, you have my full support though, good luck :)
