I am pretty much alone in becoming my true-self. I have a therapist I see on a rather regular schedule, which is great for support and getting through the hurdles we need to jump through. I have my parents who are also supportive, but they don't know to the full extent I intend to transition and nor do they understand the full extent of what it means to be transgender, but they say they love me no matter what and they just want me to be happy - plus they said they'll always be there to talk too or a shoulder to cry on if needed ..... only issue is they live quite a distance away. As far as immediate family, my wife and tween-age daughters are completely against and very unsupportive, to the point of transphobic. The few friends I've come out to have been mixed, with some not even talking to me anymore and others are okay, but the friendship has faded to distant at best. Many other friends I am assuming will be much the same as none were ever super close friends to begin with. My extended family (brothers/sisters) I think will be fine, but they all have their separate lives now and live several hours away from where I am at.
I am looking at getting involved in some of the local support groups and making friends through them. I have also recently taken a job as my true-self and look to make some friends that way as well.
