Hey there, brave fighter. I know things may seem rough these days and I know things may not work out the way you want to, but trust me, things will get better. Remember, self-harm is never the answer. Being the fangirl that I am, Calum Hood once said, "If cutting yourself meant cutting the ones you love, would you still do it?"
Think of all the stuff that might happen, not only to you, but also to the ones around you. I may not be around forever to listen to all your problems and be there for you, there's someone who won't bail. God will always listen. He cares. Don't think that no one would even notice, you're wrong. Those who care about you will. Don't be afraid to show your true feelings. It's a sign that your brave enough to say what you feel. Hang in there, brave fighter. Things will get better. Maybe not now, but soon.
