Feeling welcome in community groups

It important to belong to community groups as a way to learn and raise awareness just by showing up. Sometimes the group is not receptive and it's best to just move on. I belonged to one such group that I did not feel comfortable with no matter what I did. I was welcomed and spoke twice- a member of a panel and a presentation. First was the talk "Strategies for hiring employees with disabilities." I developed a power point and spent 30-45 minutes talking on the benefits of hiring and workforce engagement. The beginning was an activity and the conclusion was for comments. The participants hardly said anything either time. Did I expect too much? The second was a panel on diversity. I recalled the experiences I had as a placement specialist and job coach. The moderator made something sound funny that wasn't. It was not appropriate and I felt really uncomfortable. Then the diversity group I was excited about had meetings without me. They would send the summary after the gathering or cancel but not inform me. I realized that after a year I was not going to make any more inroads so I decided to seek a different group.
