I can't say for sure but that sounds like someone that's more likely to happen during a manis episode. Either way, it sounds like you're dealing with feelings of housing instability and wanted to feel more in control. I know how that feels. If you still feel ready to move out when you're low, that's how you know you're ready.

We can underestimate how abrupt we come across to other people, which can make them scared or confused. Good luck.
