I feel like my family is ashamed of me

I got out of high school 2 years ago and up until 2 months ago I found a good job that pays good seems professional and is really reliable. I was so happy I found this job because it goes with my career choice. Between those years I was trying to figure out what I was gonna do with my life and I finally did. However I’m the youngest of my siblings and I know my parents are getting older and my dad gets tired working so hard. For a while I was thinking of not going to school and just working until I can have enough money to live good enough. In order to be able to hopefully get my dad to stop working. I’m barely getting the money flowing and I’ve been helping pay some bills but I’m trying to save most of it to try not to live paycheck to paycheck . I overheard my dad telling my sister how he’s getting old and he’s tired and no one helps him with anything and he’s the only one carrying this family. It makes me feel so ashamed of myself that I’m not able to do what he wants. I know he’s tired, that’s all I think about whenever I think about my future. I’m trying to make an actual plan so we can stop living paycheck to paycheck but he doesn’t see that. He’s mad at me because I told my brother to take out the trash. He’s 27 works like 4 hours a day the rest of the day he sits in the couch and doesn’t get up unless to eat. He helps pay bills to but runs thru his money quick even tho he makes more than me. It makes me mad that my dad complains of how my brother lives but never ever tells him anything or like when he was younger discipline him to be more responsible. I feel like I’m the only one that cares enough to be morey concerned of our future that I rarely have a happy moment in this family. I’m so tired of always hearing the same things and not being able to enjoy anything because of how they make me feel. I feel so restricted and dumb. I don’t even know what’s right or what’s wrong anymore. If I should keep doing what I’m doing or drop everything to live how he wants me to. I just needed to let it out.
