Brother, your story got me deep. Unfortunately i can imagine how all of this must have felt.
It seems to me like a case of defamation, which is an awful thing.
This is just my advice on the matter. I hope that it can be helpful to you in the future: do not tell anybodi were your faith belongs.
Even if some people seem to share similar interests with you, or they act alright with you being a Zevist. Things can change from one day to the other.
This is a path were what really matters is being wise.
As you advance you can either go forward or go backwards. Some people might have done the dedication ritual but if they lack the proper mentality they will go backwards and you cannot know what they will do to you once they start doing so. Defamation, personal attacks against you, Satan, your family... you cannot know and it can happen quickly and over the stupidest things.
Therefore you should never tell anybodi about your faith, and you should never try to make it look like it's a good thing to believe in Satan. Times are not yet ready for this.
What you can do, if you find a person that is already on this path or that is genually great is to try and shape him or her towards being a better person and that's it, do not bring in faith and religion. Be quiet about this, it is for you own savety.
Another advice i can give you is to ask your guardian Demon first about this.
When i went through a similar situation i was screaming to half the Duat galaxy about revenge.
I got many "messages" from the above that i should have contatted my Guardian Demon. That helped me a lot.
If the situation is really bad you can contact (as HadesWhitin666 suggested) the God Abigor and have faith. Have faith in the Gods and do not waste any energy.
I know how this must feel, you are probably very angry and frustrated. Use this frustration to vibrate the Tiwaz Rune for example, with the correct affirmation, ot Thurisaz (even just 15 vibrations for this can help).
This will help you deliberate justice in long terms and will also help you get off some anger. I know it can become unbearable at times. Good luck with everything brother.
Stay strong.
Also, look at the positive part. Now you probably know better what kind of people to not trust.
