I might be the only one who is honest with you, but he didn't love you. That argument isn't worth it. If you like it, then who cares if your friends like that shade of lipstick on you? You don't need to prove yourself to anyone; you know what your intentions were.
Stop overthinking. You are causing yourself so much pain replaying those memories in your head. Why are you thinking about him when he is clearly not thinking about you? The grass is always greener on the other side, so you might as well decide right now to start watering your own. You are too young to worry about forever. Despite how they treat you sometimes, your parents really do love you. It's not "success" if you are stepping on people to get there. If you claim to not like beer, you haven't tried the right ones. If it seems absolutely terrifying to you, you should do it. Looks aren't everything. The only person you should give your all to is yourself.
Your friends might not always be there, but God is always waiting to hear from you. There is a song out there for absolutely everything you could ever feel. Just take the compliment. You see yourself much differently than the way others see you, so don't be so hard on yourself. You can beat your addiction. Run an extra 10 seconds, as hard as you can, the moment you decide to quit. Prayer is powerful. You do not need anyone who doesn't need you. Plant something and watch it grow. When you are wondering if you should or shouldn't, the fact that you're questioning it means it's probably not a good idea. It's very important to choose carefully who you decide to have in your life. Listen to your intuition. What happened wasn't your fault. Someone you know is jealous of something you have. Revenge is only sweet if you are. You are making a big deal out of nothing. You might work out every single day for twelve hours a day, and you will still never look like her, but THAT'S OKAY because you are still beautiful. If you are doing it out of love, you are doing it right.
Sometimes relationships end simply because you are not right for each other; you don't need to hate each other. The pain you are feeling right now will not last forever. Suicide will not solve the problem. Spend a little time alone. Ignorant people still teach you plenty. Never miss an opportunity to tell someone what they mean to you. Put your phone down for a little while. Take yourself out to eat. The things they said about you behind your back says more about them then it does about you. You have absolutely NO business judging them. Take three deep breaths. I know it feels like the world is ending, but I promise this too shall pass. Humility is the answer to everything. When someone says you hurt them, you don't get to choose that you didn't. Someone needs you. Despite the many horrible people you've encountered in this life, there are so many good ones you haven't met yet. Pick up your phone and tell them you're sorry right now. You don't know everything yet. You're not always right. Actually, you ARE beautiful. It's noble to try. Do not reply while you are still angry. Think before you speak. Just tell him you love him already. What are you waiting for?
F*** what they think. You are better than what he is willing to give. You don't hate her, you hate that he moved on so quickly. That relationship was unhealthy anyways. Whether you think you can or you think you can't, you're right. Go chase that dream you have been thinking about. Vulnerability is the most respected quality you could ever possess. If ever you find yourself victim of someone's hateful words, kill them with kindness, but don't be insincere. If you are always putting on a front, how will you know if people like you for who you really are? Stop lying to yourself; you know the truth, God knows the truth, you can't hide. You let a good man slip through your fingers because you are just too stubborn. You don't look fat; buy the bikini. A cold beer is the cure, I promise. Stop criticizing her! You're not perfect either! Love is a hell of a drug. Yeah, confidence is sexy, but settle down a little. You WILL find the man of your dreams. You don't have forever, and life can be taken from you in a moment, but that doesn't mean you need to rush; stop and smell the roses. Nothing you do will ever stop what God has planned from happening. Stop protecting their feelings. If it feels right, do it. Don't give up just yet. Everything will be okay.
