"Judy is my neighbor."
Well, it is supposed to be at the end but this is a common problem when typing Arabic in some platforms that do not correctly support the right-to-left system of writing.
You will see this problem prevail also when typing quotes (" ") and the exclamation mark (!) and few other symbols I guess. So, it's just a technical issue not a linguistic one.
Personally, sometimes I would type a letter (just anything) after the dot to bring the text back to the right alignment.
جودي "هي" جارتي. (Is) here is equavelant to هي and I dont think the sentence can be written without it.
In the word جارتي
Originally, it is جارة (járah) - female neighbor.
When "my" suffix ـي is applied, then it is attached to the Ta-Marbútah ة and turns it into T ت - and the word becomes جارتي (my f.neighbor).
