Hi Scilence, I have been seeing my T since March 2010 and am only just starting to recognise my feelings - for a long while I denied having any. I'm not saying it will take this long for you, but what I do know is the harder you try and think about it and force it the more difficult it can become.
My T recommended a book called Focusing to me early on - it made no sense to me at all and I only read a couple of pages. I have picked it up again recently and it is starting to make a little more sense.
I can relate to what you write about helping everyone else - my T is now starting to get me to focus on my needs and doesn't buy it when I say I have none - I think the two may be connected.
You're not doing anything wrong, I think it just takes time and patience. Soup
