You’re Not “Too Much”
Being scared to take up space means feeling like it’s not OK for us to have wants or needs. That is not OK for us to “inconvenience” or “burden” other people.
When we’re scared to take up space, we often believe deep down that the only way for us to avoid abandonment is to put our needs aside and make ourselves as convenient and agreeable as possible. Maybe then, if we’re easy enough to be around, others will put up with us. They won’t notice how bad we really are.
