Trans people can have any of the sexualities that cis people do. So, with your target gender being female, if you are attracted to other women, then your identification is lesbian. There’s nothing mysterious about it.
As I understand, the term transvestite is common in the UK, but it has fallen out of favor here. Not sure why, but it would take a bit of research to understand that.
Regarding resources, have you done a search for LGBT Resources in your area? Here in the US, a number of LGBT Centers offer therapy services, help with navigating the health care system, etc. Hopefully it is similar where you are, but often it is a difficult proposition if people live in smaller towns away from metropolitan areas.
