Having a supportive and knowledgeable therapist is very important, but yours sounds to be less than ideal. Any chance you can try someone else?
I also haven't been following your situation, so I'm a little unsure of exactly what's going on. Are you trying to get trans support from your current social worker? It sounds as if she admits her lack of expertise in certain areas, so I think you are right to try someone else. Have you already asked her who DOES have the expertise you seek?
I hear your frustration, but these bureaucracies tend to be designed to challenge clients in a lot of ways. They are often designed so that you DO have to go out of your way, perhaps again and again, to get what you need. Unfortunately, a lot of us trans people are feeling depressed and hopeless at exactly the time when we need to be strong and resolute and persistent. You may have to dig down into yourself over and over for quite some time to get your needs met, and you have to find other support wherever you can--friends, family, support groups, Susan's, therapist...whatever.
Even if you don't have those other resources right now, at least you have us. And what Max says is the truth. It does take time. I remember myself seven years ago--I can hardly believe it, seven years! I was a mess. I was working part time and facing unemployment, my relationship was on the rocks, I hadn't started transition, and I could barely get through the day. I was hanging on by my fingernails. I told my therapist that my life seemed impossible. I couldn't survive what was to come, couldn't see a way through. He told me that I would get through by taking one step at a time. I couldn't see it but I believed him. I had to; the alternative was to not survive, and I hadn't gotten so far after decades of struggle only to give up when things were about to change and get better.
My whole life was a constant mental refrain of I can't do this--I must--I can't do this--I must. I took that one step at a time. I did my research and wrote up my lists and made my plans and talked to people and set up my support systems. My life is so much better now. When I look back at where I was and where I am now...yikes! It's night and day. But I had to do the hardest thing: keep going even when I thought I couldn't and even when no end was in sight. If you can deal with the uncertainty, the rest is mostly logistics.
