Hi Bola,
I suggest being careful about what you tell your elders about this.
Jesus indicated that being "born from above" was a basic concept of being one of his disciples. (Jn 3:3-5) Jesus chided Nicodemus for not understanding this. (Jn 3:9-10) The reason he chided him was that the giving of the spirit was foretold to be a part of a new covenant. (Ezek 36:26-27) Nicodemus, as a teacher in Israel, should have expected this turn of events.
The WT teaches that only the 144,000 are anointed with spirit. But the two passages about the 144,000 (Rev 7:1-8 & 14:1-5) say nothing about this. WT teaching on this matter is a contradiction to basic Christian teaching as presented in the NT. And as one of the posters above pointed out, WT teaching on this is more related to WT's authority over its followers. Silencing you might be the easiest way for them to solve the possible problem you present to them. (Compare Jn 11:47-48)
So the problem you may face is that your new found realization might contradict current WT teaching. Depending on your elders and CO, putting you out may be the easiest way for them to solve the possible problems your view presents.
Since you can't prove you have been "born from above" (other than scripturally - Acts 2:38-39), and they can't disprove it, it might be best to leave your understanding to yourself. They will assume that you are claiming to be anointed when you partake at the Memorial. They will even say that YOU are claiming that when you partake. But they are assuming that you accept all their teachings about the topic. If you don't want to become controversial to them you might want to leave the matter as something you understand, but something they can take it or leave it if they question you about it.
