Lonely

So, lately I've been feeling really alone. Even in a room full of people, I still feel as though I'm not really there. I started this blog to get out all of my feelings, but it seems like the more I write and the deeper I dig, the more I understand that there's a lot of stuff that I've suppressed without even knowing that I felt this way.
A few weeks ago I was on a retreat and I was talking to this woman I trust deeply about my general feelings of loneliness. And she said to me "We will always feel alone because no one can ever truly know or complete us because they don't know our hearts and minds. Only God can ever do that."
That made me feel so...sad. Because I pray and read the bible...but I never feel like God is speaking to me...so maybe I'll just never be complete. I'm so scared that I'll never find a place where I'm whole.
