It is not your job to make anyone happy. Happiness comes from inside.
You will feel it once you “stop staring at your deformed leg.” Your main problem is that you care too much what people think and you had based yourself images in their own insecurities. STOP IT- Instead of wanting to make people happy- Determine to find your own happiness and everything else after that will change. Look at your “handsome leg” and advertise to the world. Work in your issues. You have a lot of potential that you are wasting away because you are lazy; have too much insecurities and personal accommodation. All that angry, envy, bitterness, resentment is what is making you unhappy. Wake Up and forgive. Happiness is not a constant. But peace of mind should be a habit and I can see that you don’t have it. Throw away everything that is not worth it in your life and start from zero. Reevaluate your life. Do the things that are harder to do and you will see how your life will change for the better. Your feelings will change. I know this because of my own experiences. Become a new man GROW UP AND STOP BEING SUCH A TIPYCAL AMERICAN. SEEK CHANGES.
