Help ladies just need advice

I will try not to make this too long but here's my story. I'm 21 years old. I been dating my boyfriend for 2 years. I just got a car ( which I'm still paying for) and my mom just had a baby 2 months ago. I work 2 jobs and almost never have time for anything. My mom wants me to help her a little more in the house work because it's been too much for her after the baby. My boyfriend is always complaining that I don't have time for him anymore. But right now I'm trying to focus on me (paying my late bills, finishing paying my car. Etc) I work almost 80 hrs a week, I only have Monday and Thursday afternoons off and then the whole Sunday. How do I make my bf understand that I'm trying hard and my best to be with him but I need to work because I'm tired of always being broke ? How do I make my mom understand (even though I don't mind helping her) she's not the one to tell me what I have to do on my days off ? It's frustrating idk what to do 😑 I don't have time for myself but I have to make time for everybody. I love my boyfriend but I think we should take a break because I wanna focus on me. I never have time for myself, I barely sleep , I been really tired I just wanna sleep on my rare days off 😢😭
