Suggest Treatment For Dog Bite

hello, i am a bit worried, my dog bit my finger playing around with me, and i barly bled, but i bled, im worried if i might have gotten rabies because after symptoms show, i heard that its too late to do anything, its been two days since he bit me, the cut looks fine, its not infected, i dont have any symptoms, i eat and drink fine, the only thing tht i have is tht im drowsy, but tht is because i was up all night worried the day i got bit, my dog shows no sign of rabies, my brother had told me he had gotten his rabie shots but seemed unsure at first, i feel completely normal except for the paranoia tht i might have gotten rabies, do u think i might be infected? or am i safe? p.s. my parents do not want to take me to the docter because they think im being foolish.
