I got the job but turned it down because I realised it would be very detrimental to my mental health if I worked night shift.

It's graveyard shift so zero social life with friends, my UU group, no time with my partner at all. My parents are incredibly noisy and selfish and they constantly wake abusive brother who works nights. They refuse to make small adjustments out of sheer selfishness when he asks them too and he constantly has poor sleep.

So I turned it down, citing "health reasons" and they guessed it's mental health related. :/

There might be another similar position. Doesn't have the generous shift allowance, but it starts 630am. Commute might be a problem since I live over an hour away, don't drive, first train is 545am. Even if I could drive, it's not my car and Narc Dad is still his abusive self...
