I can certainly relate to this.

In group T, when I didn't get feedback on some things, I felt hurt - like no one cared.

I, of course, felt totally unsupported....and the lesson I took from it was that I had to learn to be self-supportive because I can't depend on others to support me. Grrr.

In reality, I found out later that some people were triggered by what I was talking about and were having trouble with the feelings that they were dealing with as a result of what I disclosed.

Others didn't know how to relate and were afraid to comment for fear of saying the "wrong" thing.

I think it was very brave of you to voice what you did. The lack of feedback sucks, especially when it probably took a lot of effort on your part to share what you are going through.
