Y am I so alone ?

I see a lot of people roaming arond me. I see a lot of people walking down the streets. I see a lot of people seating around me while I am working. I see a lot of people chatting and charming in the cafe and the restaurants. I can really not understand why am I feeling so alone then ?

I do have lots of friends to chat and to roam around with. I do have lots of friends at my workplace. I also enjoy having coffee and chatting with the friends at some good cafe. Then what is the reason I am so alone ? I keep thinking all alone why do I feel so alone ? But I am not alone. It is just the fear of loosing friends that I am having all the time. Manier times I sit and try to figure it out. And guess what it is ? whoa whoa ! Some time it happens that the people you like to be with leaves you at some point of time. So even when you are surrounded by the lot many people you feel alone.

I work in a big team. But now a days I can not concentrate on my work as I used to do some time ago. People with whom I enjoyed working have left. New people have joined but i dont get that feeling. I understand as the time passes everything gets on the right place. But what do I do at the moment ? So at this time I am feeling the same things when you go to some strange place and meet the strangers. Or you are joining a new team inspite of you are the oldest member of that group or place. But then I think of the situation when I was the new member of the team. I was supported well by the old members. So am I doing the same to the new members whom I meet ? I should give the new members a chance to enter in my life. But then what ? What if some day they also leave me ? Again the same days. Same story. Same situation of feeling lonely. Then what is the solution to get out of this ???
