How old are you? You sound a little bit like myself when I was younger. The fact of the matter is, sometimes people have pain so deep within themselves, that it blinds them to the truth. How do you know your parents love your brother more than you? You said yourself you're quiet and shy and polite - maybe these things are a reason as to why you interpret peoples' attitudes toward you as "not enough".

An aura a person has about themselves isn't necessarily visible through the naked eye - but people can tell things about others without even talking to them. I thought my mom liked my sister more than me so many times because my own personal pain looked for small things - and believe me, they were SMALL - that "proved" my logic was correct.

If your boyfriend doesn't cherish you and you don't feel like you're special, dump his ass. In fact, dump him for the fact that YOU NEED TO WORK ON YOURSELF. Self esteem is so important. And it's really hard to improved a self esteem when it's bogged down by caring about what your significant other thinks of you or his flirting with other girls. No, you can only love and receive love when you truly love yourself and it appears right now that's a struggle for you because you don't feel like you're special.

You are. You're very special. Not special ed, or any stupid joke people attach to bring down this statement... you're a very special person, as we all are.

What do you do outside of reading manga, watching anime? Do you have any special hobbies or activities? Spend some time with yourself developing an activity or hobby so you can distract your mind from the negative.
