Wow that little voice in your head woke up quickly when the tree fell over didn't it?
Listen to the others on here and not to that little voice. We get manipulated so easily in the early days, heck we have to be careful after years I should think. When you have some time under your belt and you feel better (yes you will), think about the tree and ..........smile. Get the vacuum out, pick up the needles and enjoy your effort with your first tree. Place a star or an angel with your name on it on top. Your are worth it. Keep strong and keep going.
