I have found transgender support groups to be invaluable resources. I am active in two.
One is a group run by my HMO, and functions as both a group therapy session and a way to discover options within the HMO for treatment, access to needed services, and all the undocumented details on How Things Work.
The other is a social support group, hosting meetups, dinners, BBQ events and parties for trans folks and their spouses, if any. This is a great way for us to to meet other trans folks, take those first steps into the world as ourselves, and discover trans-friendly services and businesses in their community. This group is loosely connected with a local LGBTQ center.
