Everything is falling apart?

You are still doing better than my family. You and your brothers have a good support system. Your stepdad loves all of you. A couple of your brothers decided to do what they knew was wrong even though they had someone to go to for help BEFORE they decided to do it. Many people do not have that at all. So yes things are not great right now but count your blessings that you all have people in your lives that care. Life is a rollercoaster and you just have to learn to hold on when things get bad. Go to your family and tell them how you feel and that it frightens you. Your stepdad sounds great, wish he had been mine.
