I'm 29 with no music degree. I moved out to LA two years ago to pursue film scoring so take what I have to say with a grain of salt...
My experience has been, if you're persistent enough and can really embrace not knowing what comes next, you can land a job writing music and getting paid for your work. The problem is, these gigs are not enough to pay the rent. So having some kind of side-hustle is important, and will keep you from burning yourself out.
In my experience, burnout is the thing you want to avoid more than anything. Even if it means you have to divide your time in a way where you're not dedicating 100% of it to music.
Unless you're one of those people who's already established yourself, this has probably been the hardest year in human history to be a composer in LA. Give yourself a break, and know that opportunities are out there for you, if you're willing to do what it takes. Compromise is part of the process sometimes.
