Lonely... I Have No Body... Only My Own..

I went to collect my annual medical check up report today, the result shows im healthy and i am happy with it. The doctor is my regular doctor and she has been taking care of me since many years ago, so she knows about me and my bf to a certain extent and she make a comment of my bf and that make me upset.I should be happy and feel relief on the check up report but suddenly doc make a statement

"i can feel you are lonely", i was stunt, never have i thought she will say this, stunt and dont know what i should answer i said "no, doc i just love to talk to you"but at last i said "yeah, maybe you are right". Sometimes i just feel bored, sometimes i feel lonely but i didnt know that it was so bad that it shows on my face. Frankly i dont realise it is so obvious. Lonely.. how do you define it..and how do you define you are not lonely. You have many activities line up ahead, you are always busy, you always have lots of friend to company you, then you will not be lonely?Physically sometimes i feel lonelybut mostof the time i dont,i think doc is right, maybe deep down in me, i am VERY LONELY. Not self-pity but just love melody of this song and part of the lyric.. Lonely.. I Have no body.. Only My Own
