A single feeling can contain many thoughts. But the reverse is not true, it takes many many thoughts to flesh out just one single feeling.
This is why therapy takes so much time. Translating feelings into cognitive, rational thoughts is a time consuming process. Then you have to re-convert them back into feelings.
This is also why you have the whole “I guess you had to be there thing.” Someone is trying to use thoughts to describe a feeling and it’s a pretty tough job. But comedians are good at it.
