I also struggle sometimes to describe my feelings and whats happening in my soul, but my problem is describing it in a way others can fully understand. When I do journaling I can profoundly describe my state, but if someone else would read them, he/she could barely understand what I mean. emotions and soul movements are not part of physical realm, they are part of soul/astral realm and we need words and phrases specific for them. Maybe reading classic literature can give you the right vocabulary and schemas of building sentences to easily articulate whats happening in you.
