Feeling like I can't do anything right?

I'm so sorry you're having such a hard time, and that you didn't get a dress for the last day of school. Because you're living with your Aunt I'm going to guess that you haven't had an easy life. Many of us were dealt a rotten hand of life, so you're not alone. Sometimes we can't control the situation we're in or how people treat us. Your Aunt could be feeling pressure from other areas of her life and may not have anything to do with you... she's just taking it out on you. When we keep trying to do something a certain way and things still don't change, then it's time to change the way we do things. It could be that living with your aunt isn't going to get better, and no matter how perfect you become she may still be mean and say cruel things to you. Many of us kept to ourselves and held our tongue until we were 18 and could move out on our own. It's not easy, but you will survive and go on to have a good life. It's just right now it seems the whole world is crashing down on you. Keep your focus on your future. Doing well in school is the best thing you can do for yourself right now. It will help you get a good job, and help with college too. I just said a prayer for you that God would send an angel to comfort and protect you.
