Facing issues is scary. VERY scary at times. But just think of having a life where you're not defined by all the issues you face on a daily basis. Where you understand your body, how it works and the parts inside you, and you can use it to do the things you're afraid of right now. You can never get there if you're always avoiding all the issues, you can only get there by facing them.
Going into therapy, YOU are the one who has the say on how fast you go, and what you're comfortable talking about (and when).
As far as not having anyone near you, most places can set you up with a teleconference type of appointment. I live in Northern Ontario, and I can have an appointment with doctors and therapists living in large cities by going to my local community mental health place and having a face to face appointment using a computer system. The doctor I see right now lives in a small village, and yet is one of the top rated in the area for trauma and dissociation. Many people will give appointments with clients over the internet, and you wouldn't have to leave your home.
It's possible to get the help, you just need to be ready to accept it. And that takes time.

Another thing I'd like to point out is that getting a diagnosis does not change anything about who you are. If you have a diagnosis, the only thing it changes is that people now know how to help you and support you. It won't change anything about who you are. You're the same person whether you have a label or not. You just have more of a chance of success if you have identified what's going on.
Ultimately, it's your decision. Only you can make the choice, only you will go through the process. But there are some great supports and people out there to help you through it.
