I'm so happy for you!!! And a little sad at the same time because of your son. I know it's hard. I've been married twice...the first time was hell and even worse because I couldn't see my child for 9 months. It got better. I re-married and I have never been happier ( my wife is extremely supportive of my new self). It's hard and sometimes scarey, but I think you are on the right track.
I'm not that far in to my HRT (around 4 months) but I can tell you that even without some of the difficulties you are experiencing I still get a little scared of the future.
I'm glad you are looking for the support you need. It makes a big difference.
