When I started therapy, I couldn't understand the concept of shame (there was no example and no feeling with the word)....because that part of me wasn't connected to shame-I put the shameful part away 30 years ago). There were other feelings I didn't connect with in conversation-anger (I know what anger looks like) but I don't let myself feel that one much-so there is a disconnect because I was raised that anger was bad-anger kinda equated with crazy people get angry (and I wasn't crazy). When I draw my brother and how he portrays his anger......I can see the angry face, draw the angry feeling in the drawing....and the resulting feeling elicited in me is fear. Anger causes fear in me.
I had to draw the feelings of others, and then connect with what do I feel when I look at the picture. So if you want to try feeling anger, draw something that someone did to you to hurt you. Do you have a "feelings" vocabulary? Like can you look at a picture and guess the feeling of the character in the photo, what is going on in the picture, and use one feeling word to describe your perception of what he/she may be feeling?
When I was really symptomatic, I couldn't even begin to fathom feeling contented......it was a foreign concept....but after a couple of years working on this....I catch glimpses of contentment. In my writing, I try to pick one word that identifies the main feeling at the time. I think in active trauma, I knew unhappy, terrified, depressed, sad, confused, abandoned, betrayed, and hurt.......when things quieted down, and I started getting out to the park, doing art, music, photography, and excercising, then I started to have other feelings. In the house, when I was hanging in my bed alot, my feelings were more negative...and I know those feelings.
So, you want to feel something other than negative.....try doing positive, healthy, happy things and write or draw after doing them. That's the best suggestion I have. Hope you figure this one out..
