My mom sabotaged my chances of getting my first job 😐. Do I have the right to be angry?

So since I have nobody to talk to about this without getting misunderstood I figured I'd just pour my emotions out on here. First off, I'm 16 years old and I don't really like my lifestyle much. I do virtual school, watch kids (my nephews and nieces) all day long (they have parents with jobs). Then I clean up my house (and get no type of thank you for it or anything.) and browse on social media. My life Is not fun at all, especially because of the fact that I never have any money and my parents don't ever give me anything even if it's just a simple request they always have a lame ass excuse. So anyway long story short I filled out several applications because I got tired of always being told no, I'd rather do it for myself. Its rare when they tell me yes. Anyway a few weeks back and McDonalds called me back on Thursday of last week. Since my phone doesn't have any service and hasn't since I was 14, I gave them my mom's phone number to call on the application I filled out. They called my mom's phone, but she missed it she let me listen to the voice mail they had left..... So mind you I'm just now hearing this voicemail at 11pm at night. The very next morning this women went behind my back while I was asleep and went down to the McDonalds (the one I applied at) with my older sister she's (26 Years old) and she made a complete fool of herself going in there talking to the manager saying that one of her daughter's got called back after applying there but she didn't know which one... Basically she was trying to get my older sister to pose as me so that she could get the job. Once that didn't work out she made my older sister apply on the computer and what not. So long story short... She went in there and made a fool of herself and sabotaged my chances of getting a job at McDonalds and they didn't even get the chance to set me up an interview and she went in there with my older sister and did that. I kept calling them like I called at least 6 different times and the man was always busy. That tells me he might have lost interest because of my mom's foolish behavior the other day. But today was the day I called back and they hired my older sister. My mom caused this because she's selfish and doesn't want me to have anything. She mainly did this because my older sister pays her money to watch her daughter while she's at work (which she doesn't watch her, I do) but my older sister recently lost her job at a plant nursery so that's why my mom was pushing her to get hired at a job that called me back first.... Just for her own selfish reasons (extra money). I'm trying to act happy for my sister but it angers me inside to know that my own mother did this to me. You guys, every person I have talked to about this said I don't have the right to be angry. Do I have the right to be angry? I think I do.
