ידידה
In short
Your name in Hebrew letters is ידידה. A Tanakh name: an Israelite woman (first in 2 Kings 22:1; 1 mention in the Tanakh). Meaning, per Strong’s dictionary (1890): “beloved”. Adding up the numbers of its letters gives 33 — the same as the Torah word גל, “heap of stones”. That number points to Torah page 33 of 354 — in the portion Vayera. What that portion is about: Three visitors at Abraham's tent; the plea for Sodom; the birth of Isaac; the binding of Isaac on Mount Moriah. The verse that begins with the first letter of your name and ends with the last is Genesis 33:14. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
