I've gone to a local LGBT+ center near me for support group meetings. I have mixed feelings about it all honestly. For a couple of years I went often. It is a mixed group of trans and non-binary individuals. It is not a therapy group, it is a support group. Sometimes it was the best and I met some good people there. I gained lots of experience with the larger trans community. I got to meet many non-binary humans as well. It was very educational for me.
But, was it all that supportive, I dunno. I often felt that I was supporting much more than I received support. The longer I went the more on the outside of things I felt. Which was kind of opposite of what I thought was going to happen. Eventually it became clear that I was not really helping all that many people there by attending. Many of the people that went there were quite resentful of me.
To many of them, I have everything that they have wanted. I have a spouse, I have a career, I have a house, I have money to pay for my transition, and many of them have none of that. Thus when topics came up, like trying to change your voice to match your insides, and I would recommend an SLP, they would roll their eyes at me and say, no we need free ways to change our voices that will be easy and will work flawlessly. When I tried explaining that was not really reflective of reality, they would get mad at me.
Little by little, I got the feeling that many of the people that went there thought that since I did not experience being transgender the way that they did, I do not really know what it means to be transgender. Which I thought was really just too weird. I mean I get it, I AM privileged. I do have lots that other's don't have. But that doesn't mean I don't know what it is to be trans.
I went to a different group for awhile. That was a group arranged by my therapist. It was a collection of her clients. Some women, some men, some non-binary humans. It was an actual therapy group, led by our therapist. That group was fabulous and nothing but kind and supportive.
In the end what I have seen, (and this comes from only the 2 groups I have attended and thus my experience is very limited and is only my personal thoughts on the matter) the free group, the support group, was filled with people who were looking for easy options. They were very much looking for someone to help them. While the actual therapy group was filled with people who were aware that there are no easy options and had decided that they needed to help themselves. Thus one group was very giving while one group was very needy.
Sadly, the giving group, my therapy group had to stop because my therapist moved and the needy group, the support group, I decided I was not in a healthy enough position to help them the way they needed.
