Nmom playing the victim again

I'm dealing with a lot of stress right now, I've been dealing with it mainly on my own, I do talk with my friends but they're busy.

I started the training period for a call center job, but I got contacted from a gas station to do the second interview. The gas station pays more but it's rotating shifts, it's also closer to my home. The call center is 1 hr and 15 min travel but I'm almost in.

The problem is that if I attend the interview, I'll be late for training and they're really strict, I could get disqualified. I could tell them in advance I'm going to be late. Another thing is that if I dont go to the interview I can't apply to that company again, so I'm stressed cause I could lose a good opportunity.

Then my Nmom told her bf about this, I already told her to not tell him about my life cause I really dont like him. My mom texted me that her bf said I should go to the interview cause they pay well. That really pissed me off, I don't want him giving opinions on my life. So I sent my mom a voice note telling her not to tell him about my life.

Later after she came home she blamed me saying she had a fight with him bc of me. Basically he said I shouldn't speak to her like that?? He's the one to tells him to go die when he's mad.

Now I'm really mad, I told my mom how I'm really stressed that I don't believe I can do this and I think I'm gonna fail and she played the victim bc she had a fight with her bf. They literally fight every other day and instead of helping me when I really need her she makes it about herself.

I really need advice, mainly about the interview. Honestly I should really go, since they pay more it will be easier to move out in the future. But I'm not confident about myself, so I don't believe I'll pass.
