AIO- job burnout and skipping work

am i overreacting? (i have to be careful due to privacy laws. sorry if this is confusing)

house a: just a few blocks from my house

house b: across town from my house

i have a decent job working with individuals that have disabilities. i work in their home providing care. i cook, clean, pass meds, and interact with my clients. i recently was moved to working 2 homes, my issue with this is that it’s at the company’s convenience. i have some transportation issues due to a pretty gnarly home situation and these transportation issues were recent.

i have to walk home from house A on sundays late at night (12am) and i also work at that house on wednesdays. they also had me sign a contract for house B without running anything by me and told other employees they would be moving me back to my original house A. my clients in house B are low functioning, and one of my clients has some pretty extreme anger issues. they continuously yell at staff and they’re very demanding and needy. i’ve been completely burnt out since working at this house.

my managers have had no advice other than to attempt to take the bus, the last bus runs at 11pm and i live in a somewhat small town where uber doesn’t run late. they made the decision to entirely move me over to house B even though they put me in limbo about potentially moving back to house A. they told me it’s my responsibility to figure out transportation, which i understand, but the ONLY option is to walk. every time i mention something about hours or my transportation issue they always mention how i signed a contract. i only got moved to this house for convenience reasons initially and it was working out for a few weeks being able to alternate and walk home.

i’ve been making a habit of calling off of work every few weeks, and tomorrow i’m missing a mandatory meeting because i just thought about it at 3am and i’m out of town. i can’t afford to take on less responsibility (part time, losing my job, searching for a new job, etc.) as i’m the primary breadwinner. i’m just completely burnt out and i can’t tell if i’m just overreacting.
