Some people want to go crazy because they think they might go crazy and forget all the pain.
People spend their whole lives pursuing the people and things they want. Some people will keep trying, while others will give up or even go crazy if they can't catch up.
If one day you suddenly wear it and find that you in that world have everything you didn't have before, and you will live a new you in the future, but you have lost what you originally had, no matter how unbearable it is to you, will you choose to stay or wear it back?
The person you love, the person who loves you, does not necessarily only exist "now", but as long as you are willing to love and be loved, no matter when and where, no matter what the world becomes, even if you are crazy, someone will still love you.
