Welcome, Thomas the Bill Engine!
I hope for your sake that you haven't been baptized. I was baptized at 14 due to pressure from my mom and the "brightly shining ones" who conducted my free ("It only costs your life") home bible studies and other elders in my congregation. My dad had decided that for him the best route was to split and pretend he wasn't married and had no family.
It is normal for teens to find that they sometimes disagree strongly with the opinions of their 'rents, but try to pause at least once a day and be grateful that your Dad did not abandon you. Also, be sympathetic to your Mom's devotion to a pathetic failed religion that has convinced her that IT can provide her and her beloved offspring with eternal life in a paradise earth. You will have opportunities to resist her silly religion, but never forget that YOU may play an important part in getting your Mom out of her foolish delusions.
I am an atheist. I do not believe there is any such thing as a "spirit realm" populated by gods, devils, angels, demons, "holy spirit" or any other thing that human beings imagine.
You may not agree with me -- yet. That is OK by me.
I urge you to be involved in NO "theocratic" activities. No "Ministry School" (take debate and public speaking classes in school if you can - these are useful skills, but you don't need the baggage of JW mysticism that come with Kingdom Hall activities. NO "Door-to-door" ministry. If you are forced, walk as slow as you can and leave magazines at every single door you come to - but "forget" to ring the bell or "witness" to people.
...more later, perhaps.
