I think it would be a good idea to pursue the Skype idea with professional support. Please speak with your GP and see what you can work out. From what you have described you are still struggling so much from the abuse you suffered as a child, and finding a psychologist you feel comfortable with would benefit you so much, and help you to move forward.
Even if you were to visit a larger town to speak with someone, try to reach out in a new direction and see what it brings you.
In our cultural blend, it's completely normal for adult kids to live at home with their parents, but the relationship changes. They are not children any more .... it's something I refer to as intra-connected .... everybody helps, everybody contributes to the communal good of all, because more is achieved that way. I am sure you help your mother in an adult role. That is being independent .... you just choose to be independent together ....
