Anxious about others being ill

[LifeonMarss]

so I’m looking for advice really and slightly worried it will make me sound like a very selfish person. For background info I have OCD and anxiety around health.
yesterday morning my partner came down with an illness, he says he feels fine he just has the runs and his stomach feels sensitive but it’s made me so anxious.
my brain has managed to convince myself he’s loads worse than he’s actually telling me (he is the type to down play illness) and every time he got up in the night I’d have a panic attack thinking he’s worse than he is, I’m going to get ill as well etc. because I’m so anxious I’ve been quite unsympathetic and I feel awful about it and really selfish.
I have no idea what to do, this has happened before as well, I just can’t deal with people being I’ll as it makes me so anxious especially because now it’s been over 24 hours. Currently resisting the urge to bleach everywhere as this is an ocd compulsion I often have.
any help/advice is appreciated

When you say ill, are you using that as a euphemism for vomiting OP?

If so it sounds like emetophobia.

I would do whatever will relax your anxiety. If it means getting the bleach out then so be it if it will calm your anxiety.

No thankfully there’s been no vomiting so far. for lack of a better word it’s been almost 48 hours of diarrhoea
