Struggling While My Younger Brother Thrives – How Do I Cope?

I'm feeling really low seeing my younger brother succeed while I’m stuck in a low-paying job with lots of responsibilities. He has a high-paying job, a freelancing gig, and seems genuinely happy, while I’m constantly anxious about my future. My family gives him a lot of attention, and it makes me feel even worse. I know I shouldn’t compare, but it’s hard not to. Has anyone else been in a similar situation? How do you deal with these feelings?
