How Many Feelings In The F Line?

In a model, can we have multiple feelings in the F line? I have understood that for each thought that you have, though they may seem similar, you separate them and do individual models on each thought. If thoughts create feelings, then when I am writing a model, can I use multiple words to describe what I am feeling? For example: This thought makes me feel sad, horrible, lonely. Can I do that or should I only use one feeling?
