My life just sucks rn and I need somewhere to rant abt it

If this sounds childish, it's bc I'm 13.

My friend recently decided to start vaping, despite him having asthma and being overweight, so now I'm stressed af that he's gonna kill himself doing that, and I'm desperately trying to get him to stop. Another friend of mine is as worried as I am, if not more, about him, and she doesn't handle stress well, so I'm worried abt her. A third friend of mine has health issues that cause him to pass out if certain things trigger them, and he has the flu rn which apparently means that he keeps passing out randomly and having hallucinations do to this, so I'm worried af abt him as well. I can't fix any of these things though, so they're just adding stress to my brain that I rlly don't need. My house is also full of stress, bc my bro and my dad won't stop fighting and then my mom starts yelling at both of them so everything is toxic and tense and stressful. I'm usually a straight A student, but I'm currently failing multiple classes rn due to missing work that I'm not doing bc the stress of getting it done makes my already failing mental health worse, and as soon as my mom checks my grades and sees that, I'm screwed. I have insomnia and am incredibly sleep deprived 24/7. I'm suffocated and unable to be myself bc the moment I take off the masks that I wear, my life will get 10x worse. Idk. I js needed to say this somewhere.
