Maybe I'm not good enough

My two siblings have it together. Although they both went through a divorce. My brother remarried and my sister will be shortly. Here I am 28 good job no kids and still roaming this earth trying to figure my way. Ha I probably seem like I'm not gonna grow in life and find someone I often think they think that about me. They have there homes...I'm still at my parents. Black sheep sucks I often dream of just surprising them and throwing the dueces but I don't even know anymore for myself anybody feel this way or have?
