I need advice

Hi I hope whoever read this is doing fine also sorry if my english is bad and if I'm typing this like an essay soo straight to the point my family were doing fine outside and the only people I can trust is my mom and my sister who sadly pass away and my mom had to go to other country to earn money and she let my sister handle all the work which kinda sucks and when my sister passed away because of asthma I have no one to trust I can't just tell my mother because she's always busy my sister got pregnant and my brother well he sucks because everytime he and his girlfriend fight he vents out his anger on me and my dad well his focused on his job and his phone and I really need an advice I have no one to talk to, I have no friends, I'm depressed and I have social anxiety, and my classmates always talks behind my back even though I do my best at everything so I'll take any advice and sorry for bad English
