To the people who "care too much" about people who have left them or never stayed to get to know them, I am proud of you. You may always care about them, but know that it's not your fault they missed out on an opportunity to get to know someone who is as great as you are.
To the people who "care too much" about academics, there is nothing wrong with wanting to succeed. I know some people may say that you're too focused or that you should lighten up and have some fun, but you are focusing on something that is going to better you for the future. Never let someone try to convince you that your hard work isn't worth something. Everything you are working on has a purpose and I'm proud of you for wanting to do great things.
To the people who "care too much" about music, play on. If you love music and it's your passion, don't let others tell you it's a waste of time. If music allows you to express why you are the way you are, or why you do certain things, keep showing the world through your compositions.
To the people who "care too much" about people who don't want them, it's going to be okay. If you think that no one will ever want you, know that someone will. It may or may not be soon, but know that you are not alone. You have friends and family who want you in their life and they are happy to have you around.

To the people who "care too much", you are allowed to feel what you want to feel and never let anyone tell you different. They don't know how you react or respond to certain events or people in your life. If you feel strongly about something that someone else doesn't, that doesn't mean you're weird or too emotional. I know sometimes it may seem like caring so much can cause you heartache or problems, but keep caring because there are people out there who are grateful for your kind heart and your thoughtfulness.
