Don't be so down on yourself Korlee. Everyone goes through rough patches.

When I started out, I can't tell you how many times I tried to get myself to go
to a group, or out to a store. Only to get all the way there and chicken out...
drive around for an hour and still be unable to find the courage to go in. Heck...
sometimes I didn't even make it out of the house. It can take some time to
build that first little bit of courage when you're doing something new.
.
For a support group, I'd suggest just going in male mode at first. See how safe you feel,
how comfortable you feel with the people who come...get your toes wet in the
shallow end of the pool. Once you feel safe and comfortable somewhere, you can
start to open up from there.

After trying the first trans-group that I didn't like much, I tried a different type of group. There is an LGBT discussion group in my city too. (mostly LG issues, but some very interesting discussion). This was, gosh, only about 18 months ago. This was after coming out of a horrible 7 year marriage, and then being a hermit for 2 years. I went to the group a few times...but never said one word. A discussion group...and not one single word. I just couldn't get myself to do it. The people were nice. The topics were interesting. I felt safe enough...but I just couldn't get my mouth to move. I know what it's like to be terrified to speak in front of people. It can be very debilitating. They never pushed me to speak, or did anything to make me uncomfortable at all. I eventually left the group because I was afraid of making other people uncomfortable due to my absolute silence.
.
After that, I went to a different trans group, which I've been going to for 10 months now.
In that time, I've seen people come in that were starting from the absolute beginning, and now are out to everyone (work/family) and are well past where I'm at. Everyone travels at their own pace.
Personally, I travel at a snail's pace compared to most of the people in my group.
I feel a bit self-conscious about that at times, and it does often seem that I
barely make any progress....but over time all those little bits add up. I'll finish the
race eventually...but it will be on my own terms and in my own time (slow and
overly cautious as that may seem to others).
.
I'm wondering what sort of bad things you've heard about support groups?
Some are better than others certainly, but I haven't heard of anything so horrible
that they're not worth at least a look. Worst case scenerio is that you've used
an evening to find out that a particular group isn't for you. Best case scenario,
you find somewhere you like going.

Have patience with yourself, and give yourself time. If you change your mind in the future, at least you have some options available.
