Never say something is gone for good because it cannot just disappear. It's just lost or missed placed. You have to give the time and effort to go find it because in the end it's all worth it. If you want something so bad and you are willing to work it out then go find it. Nothing is gone for good, it's only lost. Whether it is a physical object or feeling, they cannot disappear. But if you keep thinking it's gone for good then your MIND will make you believe that and then there is no hope in finding it.
Remember that God loves you and even though sometimes it seems like he isn't listening, he is. You were created for a reason and sometimes that reason may not be clear. It's simple, you are here to live and serve the Lord. You are the only YOU on this Earth and everyone makes up the world. Never think that you are worthless.
Always put yourselves in other people's shoes before judging them. EMPATHY is the only way to really understand someone. When you judge others before you actually get to know them, you may just miss out on some of the most amazing people other there in the world...being different to one another is better then being the same!
In the world today, people change. Sometimes more quickly than others. Some may like it and others may not. But I guess, you always have to try to understand the other person even thought it may be hard. Rememeber though, don't forget who you really are and what it is about you that others like about you.
