Hello LillyC welcome!
Many of us here have been in your footsteps before. I can't say I was because I was born in, but there are others who aren't. Anyway, before joining, I suggest you take a look at both sides of the equation before making a formal decision. Look at the history, past and current teachings, the positives and negatives, the different experiences people have, do some research. Jwfacts.com is a good start, and of course you have the official website Jw.org. There are many different ways to interpret the Bible, and the Witnesses have many unique ones compared to mainstream Christians. In the end, the decision is yours to make to join or not, but there are many people who will gladly help with questions.
