Keep in mind that Satan and the Gods are extremely busy at this time. It is not that Satan does not know you are there, it is simply that he has many things he must take care of and he needs us to be strong and as independent as possible right now. You also have to remember that when we first start out as Satanists, we are often very closed to the spiritual world. So it could be that you are simply not spiritually open enough to sense his presence. Often he communicates to us who are new in subtle, unexpected ways. Keep a sharp eye out for coincidences. Begin a meditation program to open and empower the soul.
As for becoming closer to Satan, I feel a helpful thing to do is meditate on his Sigils and image. Simply focus on them, clean your mind of everything else. This can fill you with a very blissful sort of energy. Focus on that feeling and energy, let it fill you. Remember that he is here for us and loves his own. We each build our own relationship with Satan, whether it be to worship or not, see him as friend or father, ect.
Right now, if I were you, I'd focus on meditating consistently. Satan will come to you in time, when you are ready.
HAIL SATAN!
