Hi Sunny! Yes, you need to practice but you also need to understand what is going on with yourself. This understanding will help you to fix it.

Do you think that you want a crystal ball to ensure that you will be safe? Because of what you have experienced you never learned how to protect yourself with boundaries. All of this can be learned! Once you learn that you can protect yourself (and that you can chose safe people) you will feel safer just letting things happen and relaxing.
