Hi Rosalie,
Simple bit first, no to links, but addressing the location as you have is fine.
Everything you wrote, just about, I have been through, worst is my family now is wife and kids and grandkids... but the fears of alienating myself and possible leaving issues for the family has been my main blocker in finally becoming who I am till recently, and I still have not worked out the best way of handling the event yet... But like you I have spent my whole life crying and weeping about what should have been, then coming round and marching on, luckily my work kept me sane all through...
I think in your case, unless you have something that would fully consume your mind and stop your pain, I would seriously try and work with a counsellor/Gender Therapist... I really have no idea how, despite work, how I kept myself from imploding, but just telling someone, a very close transgender friend, just cleared all the crap from my mind, she will help and support me if it really goes bad.... so just opening up to someone will relieve a lot of the pent up emotions. And also will really help you be 200% sure about your path ahead. If I could replay my life, there are a lot of things I would not have done, I just tried to conform, because that's what life was about way back.
Not sure if any of this helps, but please talk with someone, in person...
hugs and X's
