Is Houston a good choice?

I'm 22 male and I'm currently in Northwest Florida in a small rural town. I live with my parents, they are wonderful parents, I work with my father, he is a hardscaper. I been working on and off with him for several years, since I was 17 years old. Unfortunately he has an alcohol addiction, and possibly a mental health problem due to a traumatic upbringing. I cherish the opportunities that he has given me. Unfortunately I developed an alcohol use disorder, I didn't want to be a burden to my parents, and watching my father continue to drink, depresses me, and recently I had relapsed, to the point where I have abandoned my hobby (boxing) and my education as I was attending community college. It's not too late to try to fix my grades, but I believe deep down in my heart that this is not the place that I want to be. I want to start my life from scratch without the help of my parents. When I was sober, I went to the gym with my brother,I went boxing, and I worked with my dad and his crew. And I went to college as well. I believe that I can do better in a bigger city. I can work full-time in outside labor, practice sobriety and get my life back on track. What advice would you give me if I were to go to Houston. And try to find a job to work full time until I can find a place to stay? Is it doable this day and age as I'm starting to run out of options because I'm only getting older?
