Do I Have The Right To Be Mad?

i dont know if i have the right to be mad, or if im just being a b*tch, but im getting so annoyed with my dad. i know its typical for a teenager to get mad at a parent, but its getting out of line. my dad gets mad at me literally every day. he always finds something to bug me about. i made him a list of HEALTHY food to get tomorrow, because I'm going to be doing chores at my aunt's to earn money, and he made it a big deal. he kept saying "im not your servant!!! i have things to do!" he has a doctors appointment that day, but i asked him if he could do it after. he still made it a big deal, and then we started a fight. he gets mad at me because i forgot to feed my turtle, which i would understand why he would get mad, but he continued to yell at me and wouldnt leave me alone and i almost felt like i was being picked on. THEN he got mad at me for drinking his juice, which i dont know about what you guys think, but to me thats soo f****** stupid. plus, he gets pissed when i ask him to get cue tips, shampoo, and conditioner! he says i need to pay for that stuff, but im only 15 and i dont make that much money. i just think his logic is off, because that stuff is neccessities, and its just annoying how he refuses to pay for simple stuff like that. i pay for my makeup, face washes, toners, moisterizers. but this one time i asked him if he could pay for those three things and he freaked out. i just am so mad and i dont get why he makes everything such a big deal. he used to be easygoing but now hes so tense. the thing is, hes aware of how stressed i already am about my mom (shes an alcoholic and a druggy and im trying to her ignore her until she gets help for her addiction), so i thought he would understand and not make me EVEN MORE stressed. do i have the right to be mad?
