never had closets large enough to fully comfortably sleep in but yes have spent time hiding in closets as it has felt like the safest thing to do at the time.

If it helped you to feel safe then I applaud you for taking care of yourself through a meltdown.

So what if it is strange?! Until you have more coping mechanisms in place and more support in place you need to use what you know and for you this was something familiar and comfortable to turn to. Strange or not. Maybe it is only strange to ppl who aren't survivors of abuse (physical, emotional, etc)?
