So I'm hard of hearing and neurodivergent. I don't use a hearing aid because they are expensive and I only have mild hearing loss (50% on one ear). If there's background noise and I'm far enough away from my mom, I won't hear her when she calls for me in the house. If I'm super focused on work, it's worse because I tune the world out.
Both these things were happening when my mom angrily called my cellphone asking why I didn't come to her when she called for me aloud several times. Her blood sugar was dangerously low and she could barely reach her cellphone. I scrubbed her back with peppermint oil since it helps with the fatigue and profusely apologized since she cried and said she could've died and I would've known.
She's better now after eating a meal, but I still feel bad even though I always tell my mom to keep her phone nearby in case she needs anything.
