Dear you,
I want you to know that you are not alone. I'll be honest. It is going to be hard. You're going to experience the worst pain in your life. You might cry yourself to sleep a lot of times, you might scream, throw things and even think you're not worth it—you'll realize soon enough you are. Always remember, "There is always sunshine after the rain." I promise you will get out of this. But you have to go through the pain before you have the strength to see the sunshine.
Because it takes one to know one. I know your eyes are tired, especially your heart. And the only thing that is inevitable is the truth. We get frustrated with the truth, because we all know we can't change it. Sometimes we just have to accept that some things cannot be. That is the harsh reality.
Remember that dream school you didn't get into? Your second choice might be the school that's right for you. I personally didn't get in my dream school, but I took the bad news positively and I do not have any regrets with my school now. You will find good friends, join exciting organizations and probably be a Dean's Lister! Keep in mind that when God closes a door, he opens a window.
Remember that one friend you used to tell all your secrets no matter the distance between the two of you are? People change and you have drifted apart. No matter how hard you keep on pushing yourself that you can patch things up with your "best friend," it's not working. Maybe you just have to give her time and sooner or later, talk things through. Best friends forever, right?
Remember that boy who left you for someone else? Who told you he'll never leave you but left, anyway? If only we could stop our heart from breaking. Let's just call them our Robin (from How I Met Your Mother), that person we loved so much but cannot be with. "And whoever you'll meet, whatever you'll do, nothing will be like Robin." But we love them so much, and we must let them move on.
We may not be as happy as we always dreamed we would be but let's just allow ourselves to be whatever it is we are right now. That sounds like a plan, right? We all make mistakes and we must never regret making them. It is when we learn things that are for keeps and there are those we need to let go of. Remember that you are never alone and we all go through these things. Keep the faith.
