worthy?

A few weeks ago i started participating in a self help group. We’re all left the „relatively normal“ sign so far behind that we can’t even see it in the rearview mirror anymore, but i have the impression that i’m not as far ahead on that way like other participants.
My therapist says it is a good thing, we came to the mental picture of a self help group being both: a wave and the surfer riding it. One tries to contribute to the well being of others while also receiving the others contributions to one selves well being.
When i mentioned that i’m married i caught some surprised glances. It seems like i’m the odd one out, and fear that the other members think of me as not being worth their time and help.
