Stop worrying, please. Stop getting angry at things that aren't worth the energy you put into staying angry.
If you're angry, let it out. Confront the person, I swear, it will make you feel better. Go to the top of a hill, scream your heart out until you feel better. It works, it will help.
There will be days when you feel as if the whole world is against you. But on that day, no matter what you did, remember that I'm not against you. If you need someone to talk to, talk to me. Tell me about it, send me an ask, I'll be there for you. I won't judge you and I'll get to you as soon as possible. Anon or not, I will always be there for you. Just remember that.
There will be other days when you feel as if nobody loves you. Remember, I love you even if I don't know you. Even if I don't tell you, I love you a lot, so much, more than just to the moon and back. I'll be there for you during the times when you feel unloved.
Lastly, there will be days when you've had a great day and you just want to jump around. Even if, I want to hear about it! Send me an ask, I'll fangirl with you, I'll be excited with you. Heck, I'll even jump around with you even if we're halfway across the world from each other.
Just remember that, no matter what you're feeling and you have no one to talk to about it, I'll be there for you. Just send me an ask. I won't judge you.
