Needing positive stories:(

I just recently had a miscarriage on July 15th. I have knew how bad a wanted a baby but I can’t explain how much it hurt when it was gone. I’ve now realized I’ve never wanted anything so badly, I keep telling myself everything happens for a reason but it’s hard to stay positive. I just keep asking myself why? And how? Why did it happen to me? How can someone do great be given to me and just taken away? I was only about 6 weeks but it’s still so heart breaking. We have immediately started trying again and I am in my fertile period now, so we are trying and waiting. Has anyone gotten pregnant after a mc? How did you not stress and stay positive? I need advice and positive thoughts!😭
