Welcome Kitten. Please take your time and enjoy your journey.
You are still young and have plenty of time to explore. Faith and spirituality is a very personal thing. You will have to decide for yourself what is best for you.
I do agree with the advice to do your own research before you commit to any organization religious or other wise.
If you choose to believe in a higher power, that is your personal decision and choice. There are many people of faith who have a balanced and happy life.
There are also many who choose to live a life of logic and do not believe in a higher power and are happy with their life.
I personally believe you need to be balanced and open minded what ever path you choose. Just be true to yourself and dont allow anyone to bully or influence you from what is best for you. Remember take your time.
Have an exciting and enlightening journey.
Miss Fit
