Why get rid of it if it still fits and will fit? You will be out on your own one day and have all the room you want.

Maybe get rid of stuff you don't want anymore. But don't purge your stuff out of fear of everyone else (unless that fear is founded).

I mean it sounds like your family probably knows anyways if you really had THAT much stuff in such a tight space. Still hide it if you arn't ready but don't let your family ruin your fun and possible personal growth. It's none of their business if and until you come out and make it their business.

You are 28, a grown adult who can make their own choices, take that stress off and do you within reason :)
