Imsuster is a combination of the words Impostor and Sus which when put together makes Imsuster so when saying "when the impostor is sus" you could instead say "When the imsuster".
churchhurt is where you experience a degree of distance, pain, or judgement from your church community. Essentially, you are just unable to “find your place”. This is prevalent in the Christian community, but can be extended to other religions.
Now that I am an adult I am beginning to heal from the churchhurt that was inflicted on me as a child.
