The only way I can describe it is it's like speaking another language. You know in your head what you want to say, but you have to translate those non-English thoughts into words that you hope your listener understands. Some people are better and faster at that translation process than others.
I really am having a hard time understanding this concept. Do you connect to song lyrics? Or a poem or a love letter?
Are you saying words don't represent your feelings?
Written words are easier to deal with because you have time and distance to process them. You read them, then translate them into thoughts that you understand and can connect with.
It's very different to having people speak at/to you. When people speak to you, you don't have the time to translate their words into thoughts that you understand, then to formulate a response, then to translate that response back into words that the other person will understand, while simultaneously deciding what tone to use, what body language to present, and what emotion to show on your face. That's if you even understand what kind of response is expected from you.
These things do not come natural to a lot of autistic people. It's why they sometimes have odd body language, or monotone voices, or blank faces etc. A lot of autistic people learn automatic responses to questions and situations for this reason. Even "I love you too" in response to "I love you" is just a learnt response. But if that is responded to with "what do you love about me?" there either won't be an answer, or there will be an answer that just sounds superficial or flippant ("I love your eyes").
You have also said using words for feelings is uncomfortable to you because they are a minefield. Do you mean you are afraid to express yourself in words because you fear getting hurt/ being vulnerable?
No, not really. It's more like trying to talk about something serious in a foreign language. The words lose their meaning because you're not expressing yourself in a way that comes naturally to you. So if you're not saying something in a way that means something to you, you just feel like you're being fake. If the other person gets joy from you being "fake", you feel shitty. I suppose people just want to be accepted for who they are, not who they pretend to be.
Think of it like having a French husband. What has more meaning coming from him - "Je t'aime" or "I love you"?
