I'll likely have a relative crash at the house I'm sharing with three other people for a couple of days soon-ish and I'm not sure what to do.

Things such as not doing laundry or cooking can be hidden somewhat.

But I can't hide the fact I have not seen the people I'm sharing the house with for more than 5 minutes in the 5+ months I've been here, to the point of not knowing what one even looks like.

What can I do to possibly mitigate this issue and avoid having my depression found out. I can't burden my relative with this, especially not during those days in particular.
