Things won't be different if you keep doing things the same way. Take some time to yourself and start writing out how you want to do things differently. Design a new life. Make some personal rules for yourself. Example: avoid negative people, be in better touch with relatives you like, be kind to small children and animals, do two good deeds for others every day, listen better to teachers you don't like, make new friends, etc.
To truly start fresh,you must completely distance yourself from whatever situation you currently are in,even if it means another state ...I know because I just did it very recently and with god's blessings and help you would get through it all,good luck !!!
It isn't too late for you to get back on track-and the reason is because God still loves you, and doesn't want you to spend the rest of your life on the wrong road. You can't change the past; what you've done with your life can't be erased. But it can be forgiven-and with His help the future can be different! This is why I urge you to repent of your sins and ask Jesus Christ to come into your life. Why live for the devil any longer? He promises a life of freedom and happiness-but as you have discovered, his promises are lies. You must make your own decision for Christ. But when you do, God promises to welcome you and make you His child forever. The Bible says, "To all who received him, to those who believed in his name, he gave the right to become children of God" (John 1:12). Don't let another day go by without making your peace with God by asking Christ to come into your life as your Lord and Savior.
Spiritually you must die. You are unhappy for the chains that hold you back. What people don't often see is that they them selves are the ones holding those chains that hold them in place. When my spirit died and went to hell for eternity after eternity I was born anew as something else. The only way to start over is to let your self spiritually die. Think about everything that brings you turmoil, bubble it all to the surface and then think about what it all means if you died right now. You are free. It's only in our minds that we have an identity. Know you are an entity and that nothing you do will ever define you.
