I highly recommend meditation. It has been life changing for me and has been proven to reduce stress, lower blood pressure and help with anxiety and depression. Control your breathing and you control your emotions, it's really that simple
I also recommend journaling. Sit down every day and write down everything that is in your head. Don't filter, just write three pages. After a while you will start to see a theme, those thoughts and triggers that are bothering you.
These two things will help you sift through your conflicting thoughts and emotions and help you deal with them. Someone once said that it's not what happens to you that causes problems, it's how you feel about what happens to you. As ex JWs, we can usually do nothing about the hand we were delt, but we can control our feelings and emotions about what has happened.
I hope that helps, feel free to pm me if you have any questions.
