When I'm dreaming and wake up in the middle of the night, I try to be as relaxed as possible so I can absorb the most happy thoughts.. It's a meditative state.. When we wake up from our sleep, I think the most positive emotions are able to come out. I think that only a fool will turn that opportunity into feeling negative.
Whatever positive emotion comes with you when you wake up, whatever dreams you want to make a reality, flow and go with it.
After I wake up, sometimes I start thinking about the negative emotions of "Man I'm far from being happy."
Recognize this feeling too, but always be happy. There's no point in fearing that you'll be alone, since the hard part of civilization is already done. No need to worry at all. There are many people like you in the world. They may have come from Ex-Christian backgrounds, or found religion to be stupid too.
Your parents just had sex and you came out. That's the reality. In Islam, DNA is made into this huge deal.. Ties of "family" and "kinship" and all this bullshit nonsense. You get to choose your own family in the world. Embrace that you might find a brother that is white, or a sister that is a hindu. Embrace the world and leave your past world behind.
I think what we fear most is the abundance this world has to offer because it's just... SO MUCH. There's so many opportunities to live our life and be happy that we think that we're made to live in this "Ex-Muslim" battered circle of living..
Your life just started. Start your journey to be happy. Life is short.
