Left Me Alone..

I seriously dont get some people...in high school,for years i've been suffering inside and since i was little,i have trouble in telling people how i felt...

I just kept to myself...then,a few people came as saw how troubled i was...back then,they keep asking me,"r u ok?"...i kept looking the other way...but i learned to share my problems little by litlle...but then,once,a few people got fed up with me and just left...but they came back but i have trouble sharing with them my problems again...

But as soft as i can be,i forgave them and let them back in my heart cause they keep telling me that they're 'there for me'...but now,they just left me again...so,who's fault is it now? is it still my fault cause i cant always look at the positive side? or them cause giving me hope? there's one thing that is clear in my mind and that is,if they dont want to help,why bother asking and helping years ago? just let me be alone then as they let me alone now...i seriously cant get them...cant they keep their words? i dont even know what to believe...if u dont want to help,then just let them be in the first place....dont give any sentimental words...
