A lot of people suspect kin of rare types to be faking or trolls. That is most likely why some Otherkin will push you away. Also, by that 'slime p-shift' you mentioned, if you meant physically, then almost everyone won't talk to you. Physical shifts are such a topic.

It’s tough being such an unusual kintype, but it feels so real to me :/ I wish someone would understand.

I suppose I was quite unclear about my p-shift. I meant a phantom shift, not physical.
