Feeling Fragile and Unstable

splitting is basically exactly like you said, you start viewing things as either entirely good or entirely bad there's no middle ground. An example would be you absolutely loving someone or something to absolutely despising them now

Currently going through this. Splitting is characterized by black white thinking including idealazion and devaluation of any aspects of your life mainly including relationships.

You might be splitting, maybe not on anything or anyone particular but it seems like your going through the process where everything you like you start hating even if it's temporary, the only thing I can say to try and do is talk with people you feel close to or do things you still like to help keep your mind focused on other things
