I am embarrassed to face my friends and strangers with a broken middle finger, for fear that others will see me. My future is over.

Put your hands in your pockets and pretend to be cool if you want to reach out. The key is to adjust yourself. When you can relax and accept the reality, it will be fine. Don't care too much about other people's opinions. Be true to yourself and you will live a good and wonderful life. This is the biggest rebuttal to those bad opinions of others. No one wants to encounter such a thing. People who really understand you, encourage you and have no prejudice are the ones you really deserve to make friends with. You will get what you have lost, depending on how you deal with it. Come on, good luck.
