So this is my own story, but almost the whole cast is POC.
It shows the struggles of mental health, childhood trauma, negligence, poverty and such. All these issues are being represented by someone who has experienced such things. As well as the struggles people can go through trying to get forward in life because they can't read and things like that, which is a very big problem for people in my country.
I myself am Hispanic, as are my leads, and I've experienced first hand growing up without enough food, with depression and loved ones with depression and social anxiety and such, and I think it's safe to say I am not silencing these ideas in the story. It deals with dark, scary and challenging topics, so if that's what you're looking for, you could look at "Damsel in the Red Dress."
I'd also suggest "Rescue Me" by Sharean Morishita. It's about a woman living in an unsafe living condition with her father who struggles with alcoholism. It's not overly graphic, but it it does address these topics while promoting the importance of taking care of yourself, your mental health and safety, no matter how much you might love the people mistreating you.
She has another called "Love Love Fighting" (better than the name would suggest I assure you) that addresses issues of size-ism in the media.
