I'll answer...if it could even be considered an answer.
I too have a hard time understanding what it is that I'm "feeling". I know when I'm angry, or frustrated, or ticked off at someone or something, but outside of that I just get confused. Oh, wait, I do know nervous, anxious, and fear.
Emotions confuse me. I've smashed them down, choked them down and suppressed them for so long, I cannot identify them.
I guess it will take time to learn to have emotions, and to feel safe enough to let them out.
