What's not to love?

I don't know what to do anymore. How is it that we can be surrounded by people, talking to someone and yet, still feel so lonely inside? It seems like everything I do ends up being wrong, even if I started with good intentions. I feel so small. So very small and insignificant. Have you heard of the saying, 'To the world, you are just one person but to one person, you are the world'? Who is this person..I wonder when will I meet this person? Is this person already in my life, hidden? I wrote my mom a card telling her that she loves more than she is loved, for noone's love compares to hers. Now I hope I did not say the wrong thing. I don't want her to feel unappreciated. If what I wrote to her was true, mothers must be the loneliest people in the world. Giving out love and receiving a minute amount in return. On the subject of love, what IS love? Is it love when you get butterflies in your tummy talking to a guy? Or is it love only when you don't get those butterflies anymore? Is it love if I help with my brother with his exams...and when he does better than me, I feel a slight twinge of sibling rivalry? Is it love when my mother tells me I am too fat and that I should lose weight or no one will like me? But Mother, I want someone who will love me regardless of my weight. Is it love when you wake up each morning and your thoughts are only about one person (rendering you non functional for all other activities of daily living)? Is pre-marital love prohibited??LOL @ pre-marital love. I am so witty and since there is noone to appreciate my wit I shall LOL on my own. I am being cynical there. Don't get me wrong, I am not begging for sympathy, just someone who can clue me in on this marvelously complicated topic. I imagine myself to be the lonely old woman with a bunch of cats, living in a huge mansion...except I don't like cats so maybe switch cats to books. yeah...me and my beautiful mansion. Sucks to you for not loving me...or you could be living in my mansion or coming over for tea. My messenger list is full of people I don't talk to. Friends from school, friends from uni...I've started deleting people. The other day I did an experiment. I put: 'I shaved my head bald!' on my messenger status and suddenly, so many people started IM-ing me asking if I had really done it. Firstly, I wear hijab, why do you care anyways? It's not like youre gona be seeing my bald head. Secondly, you dont even TALK to me but you care about my haircut? Thirdly, you all forgot my birthday. Lastly, go away I'm deleting you from messenger.
Can you tell I am an angsty teenager in this post?
