Open Question: Is there something wrong? Am I Depressed?

I am a sophomore in high school. i get pretty good grades and i used to think that my life was okay, but in the past year things have gone downhill. i have friends, but no really close ones. there is no one i have a close connection with, someone i could talk to about any problems i have. i hate the way i look and i always wish i was thinner. no guys like me. i see my friends flirting with guys, or even just have guy friends, and i feel like no guy wants to even get to know me, like im the awkward person out. my parents do not get along, they got into a fight and my mom recently told me that she is through dealing with my dad. they haven’t spoken in over two weeks and its hard for me to come home and see them ignoring each other. i feel like we are all seperate. we never have sit down family dinners or just hang out, we just all go about our own business under one roof. my family is always yelling at each other and i am constantly surrounded with negative energy. i see my friends laughing and having fun with their parents and siblings and it makes me sad knowing i now dont have that with my family. i guess i just don’t know what to do. I have recently just been breaking down into tears with no specific reason. i always feel lonely and hopeless.i guess i’m just wondering if there is something wrong with me, like im missing something. i feel alone with no one to talk to. does it sound like i’m depressed? what should i do?
