Am i depressed?

i’m always so lonely inside my mind. i have friends, family, i have both my parents but i’m always so depressed. i feel no joy being around them, if i do it only lasts for a short period of time. i feel so useless, that i’m doing nothing in my life for me. i just live to live, i only live to not cause any problems for my family. i wish i could describe how i feel in depth, but i don’t know how to explain it. hopefully it’s just that i’m seeking attention
