we're temporary and you're moving further out of sight

i’m just over everything. i don’t know what to do anymore, or how to move forward with my life. i just feel stuck. same routine - wake up, work 14 hours, eat, sleep. i work so much because i figure what else will i do with my time. i have so few responsibilities outside of work, it’s not like i have a family or ever have plans after. i barely leave my house, and i don’t make plans with people. i feel like i have nothing in common with my friends anymore. they’re all married, some have children, and i’m just by myself. i just feel useless, like i’m taking up space.
