One time I slipped and fell on concrete and messed up my back so bad I couldn't walk for two days before she insisted I still attend figure skating lessons because she had already paid for them and I would be an ungrateful wretch if I missed even a single one.

Exact same thing when my SO (donp) broke her arm, when her feet were getting cut up by shoes, etc; it's not that bad, get up and get on with it.

My SO greatly downplays her feelings now, but she does it badly I guess? Will say she's ok when she's obviously hurt/something's wrong. I've only noticed it a few times, otherwise she acts it well. Other day SO burned herself at work on a panini oven and she told nmom. Nmom's reaction was "I burned myself on an iron today". The other other day discounted her stomach ache she'd had for a few weeks and is still getting (stomach acid) as 'stress'. Puts every symptom of something that could be major down to stress.

Nmom has an 'invisible illness' that effects her joints. SO has the same in her wrist. Nmom will not take her pain seriously unless she puts a wrist brace on (which helps to alleviate the pain), sometimes tells her to seek help sometimes tells her to stop attention seeking.

I have a bad mental illness that effects things I do greatly, but if I don't do the things I can't do, then I get told I am not a team player and I will be kicked out of the house for making my SO do all the work (but SO understands my situation). I get told I'm just playing my SO for a fool because there's nothing wrong with me. As a result I don't talk about my symptoms anymore to people I trust/just pretend I am 100% okay with doing the task(s).
