Oh my goodness yes - I do this alllll the time - say to her "I can't find the right words!!" And I stumble around using words that aren't quite right trying to express what I am feeling. One thing I do, is write poetry which helps me express myself and bring those with me to sessions. My t is also certified in sand play, so I do sand trays sometimes when words just absolutely fail me. I get really frustrated too because like I said I write poetry, I love words, so when I can't FIND the right words, I get so frustrated! I am learning to not judge myself for it... it's been a very very long process starting to get there... I used to sit there and stomp my feet in frustration, I don't do that anymore thankfully. But don't feel dumb - cuz you're not!! Sometimes we are dealing with pre-verbal feelings and those are soooooo hard to try to articulate.
