For those who have been wronged by another;
Instead of being sad about what's happened or the way things are, decide to get happy about the future. What's to come. Get excited. So much can happen. New experiences, new places, new people. Do you know how many good people there are in the world? Do you know how nice it is when you say bye bye to the people that drown you in drama and seriousness and put you at dis-ease... it is so uplifting.
Yes something bad happened to you, no you did not deserve it, no one does. No you won't ever completely get why and you can't change it. You aren't responsible for the trauma someone else has caused you, but you are responsible for healing it. Go to therapy if you must, it's nothing to fear - it's like the gym, but for your mind.
Life is so short, and you do not have to spend it letting others brake you. You will not die from the pain of detaching from something that meant the world to you, but was wrong for you - I promise, you won't. There's more chance of you dying from staying attached to it - do you know the physical effects of stress on the body? especially prolonged stress! How it can change the very plasticity and pathways of your brain? How it can disrupt your hormones and damage your nervous system.
Don't get sad, get mad! This is your life - it's short and here's someone expecting to be the centre of your world whilst crushing you unbearably... here is someone dismissing your god given rights to feel, to express yourself, the right to be loved, the right to privacy, the right to be respected, the right to freedom, the right to make your own decisions - how dare they!
