I no longer subscribe to Islam. I'm done with it.
Why do you no longer subscribe to islam?
I only subscribed to it when I was in my early 20s when I needed social connection.
I understand you were quite immature when in your 20's.  You're living in a free country so you're free to subscribe whichever faith you want to.
Is that so? I'm no longer a man of faith.
You can do whatever feels right to you right now. It is your life and your choices.
