I can say that things will get better, and it isn't an empty promise.
The trick is that you need to make them better. Once you realize that you can empower yourself you'll start to see things change for the better. Start to work on a more positive attitude, make some lemonade. One way that I did it was for 30 days, I wore a thick elastic rubber band and every time I had a negative thought, I would snap it on my wrist. After I got a huge welt on my wrist, my thought process started changing.
Focus on one thing you want to change about yourself, and work from there. It's not an easy process really, but you need to get started somewhere. After you pick out that one thing, go out and search for studies on it, Google it, ask strangers on the internet. Looking at things individually instead of a gigantic project can go a long way. Trust me, if I can do it, you can do it.
