Welcome sis!
Im glad you used the brains Allah gave you !
I feel exactly the same way you do. Especially when I first 'found the light'. I get passionate easily and I experienced the same hulk syndrome whenever hadith was mentioned or when anyone attempts to interpret the quran using it.
But i have learned to calm down and just chill. Its less taxing on my nerves this way! Plus i was on the verge of being self righteous and arrogant and I dont think Allah would want us to act the way even if we possessed the truth, and insha Allah we do.
As for coming out of the closet, i definetely would not do that unless you are more calm and can control your emotions regarding this newly found truth and get rid of the grudges you have against, what seems like the moshriks, around you. Or else you will push many people away from you, not because of your path, but because of your attitude. Trust me, i was this close to losing my best friend because i confided in her too soon about this. She still keeps a certain distance from me today, and we rarely ever talk about religion since then.
And like fallen angel, do it when you are confident in your arguements because you will not face anyone with this news without them trying to convert you back and prove you wrong.
Insha Allah everything works out for you. There is a lot of support in this forum, feel free to get some!
