Hello I hate to put this on people but I feel like I need some support

I'm miserable, my mom acts like I'm this horrible person who doesn't help around the house. I'm 17 got my license coming up to a year in November so I want to go out and do things with my sister and go to work and talk to the two friends that I have. I work at Walmart so anytime I go in I take about 20 minutes to talk to my favorite person because I never see her outside of work and she helps with my depression. If I'm taking to long for my mom she flips out I understand if she needs somthing in a hurry but half the time it isn't. I run to Walmart about 4 or 5 times a day because I forgot something or she wants something else and gets mad if I forgot something or if they didn't have it, I can't control that. I help around the house all the time, letting out the dogs every 2 hours about (since our dog is old she can't control it very well) and I do it but if I ask if my sister can do it for that one time everyone goes after me. We had to deep clean the house and my sister has gotten surgery just 4 days before, and she needed to be moving for certain reasons, but she didn't help at all and I did everything and you don't do what my mom wants she gets mad and flips out on you. I had asked my sister to help me feed our cat (12 cans of soft food) just open them would be fine but she through a fit about it and how she couldn't bend down even though she'd been doing it a couple minutes earlier so now she's using it as an excuse to get what she wants. I understand my mom has a hard time with some things my parents are not divorced but my dad works a couple states away so she takes care of the animals and my sister mostly I take care of myself, I pay for my own gas and things that I need I help pay for food sometimes but she gets mad when I ask for a couple dollars for a game or something when she needs to pay me back 3 thousand dollars. I dont mind not getting the money because i used that for food so i ate out of that. I dont mind helping out but when I do I do something wrong for her so I get yelled at . I go out to do something with my sister o get yelled at to come home because the animals outside are fighting she doesn't have a job she never leaves the house she could at least go outside for a second and stop it then having me drive back five minutes to stop it. I feel like I'm doing something wrong I can't talk to her about it or she yells and says I don't do anything I'm useless and a bitch for the way I acted. I feel like I have no freedom has a teenager. I'm only aloud to go do stuff for her not for me she get pissed when I want to go out and do things and tells me no. I want to talk to my dad about it but I'm not sure how. I dont mind helping, I'll help when I'm needed so I dont know what I'm doing wrong i may have a little attitude sometimes but Im in a bad mood almost all the time because of it but I still do what I'm asked.
