Don't be afraid. Read more about Buddhism .. its not a religion, but a science of silence and peace. If you learn to enjoy peace, you will learn you have a lot. We were all born with nothing - no clothes, no food - but you were lucky you had parents to take care of you. Some did not. Today you have more than many things, including friends - some you preferred not to meet with, and some you never took time to greet. Little birds do not have money, and yet they do not starve. I know you are not worried you would starve to death. You are worried of loneliness when you are getting older each day.
Remember, energy is very important to maintain life.. you can eat and drink to maintain your physical life, but you must eat healthy food to maintain a good physical life. Similarly, you need a lot of healthy spiritual food to maintain a good spiritual body.
What is spiritual food? Things that fulfil your inner self - colours, music, fragrance, touch and air (breathing) - these are the basic spiritual food, and good spiritual food become good dishes of happiness, kindness, forgiveness, excitement, friendship, Avoid bad dishes like Anger, Hatred, Revenge, Envy, Ego, Prejudices...
Now you have learnt the importance of Energy, you must follow the right way of life. Search for your good spiritual food - don't be shy to approach and make things happen. Whenever you are tempted by bad spiritual food, just walk away from it at the beginning, and learn to change that dish to a good one.
Enjoy life while its still available. Enjoy life while you still have a good physical life. Don't wait or your poor physical life only brings you poor spiritual life too.
Remember, don't be shy to approach and look for good spiritual food. I can see thats the missing part in your life. I found them in my peace, through music, through playing badminton, through cooking. Find yours now and learn to enjoy the life you have.
Patience and peace ...all this will slowly help you.. its not just words.. its real. The world is so beautiful .. not the rich American dream .. but the most common thing around you.. smell of fresh air, the music of laughter and happiness.. close your eyes, breath slowly and start to feel and learn how to enjoy. Just don't rush... its not that difficult to slow down.
