Hi Becks.Nice to meetyou!
It's true that a lot of people have gone through feelings similar to what you are going through,myself included.Keep in mind that when you were a jw,you really didn't have to make decisions on your own,you just looked up what the society said and that's the path you followed.Now,being a young adult,you are in charge of your decision-making,good or bad.So decide you want to live a good and happy life and remember life is a real adventure.
Here are 2 little secrets to help you along:
1.Be content being who you are right now,where you are as a unique individual
2.Smile,attitudes are contagious and you look like a pretty girl.try it for one day,put on a genuine,happy smile and take notice of how people react more positively to you.
Have a nice day!
