If they say that if you have an ED they will refer you to other agencies, then I think that either you could make it clear at your next appointment that you think this is a serious issue for you, and talk about being referred. They must have a particular place or places in mind since they state that specifically in their intake, and I bet this happens very often.
Or if you think that's not necessary, you could carry on seeing this T, while knowing that of the ED problem becomes really difficult for you then you will need to be referred out. I guess that depends on how much of an issue it is for you to build a trusting relationship with T?
For me, the relationship with T is a big deal, because I have attachment issues and trust issues, takes me about 6 months to begin trusting someone. So for me I would not want to start investing in working with one T, while knowing that if events took a certain turn I would have to leave and go to a different T. But I know that for some people, they don't have the same issues and maybe they would feel ok with this. It depends how you feel about it.
I think in either case, it's definitely worth talking to your T about this and both having an honest conversation about what would happen if you needed more help with ED issues. Then you will know you are both working from the same page. Also letting T know that you felt invalidated about your ED issues.
