Stress!!!

Why i am always facing so much stressin life....Why am i always the one that people throw their anger at...I have feeling and emotions too.....I have my own problems to handle as well but who will understand that???? I need support, encouragement, care and love too..... I do everything with my sincerer heart, i am willing to give full support to anyone who need my help, but what did i get at the end of the day. I am so in love with him that i am willing to do anything for him, hoping that he can see the love that i am giving him......but sometimes i start to fear of losing him, i afraid that when the day i cnt help him anymore is the day when our relationshipo ended.....I sacaracfice for him everything include money...no matter how broke i am, i will make sure he has money with him, but when at times i really couldnt help me i dare not tell him but i will try ways to sort the money for him, today he need 300bucks, i went around selling my pdts to the drivers, but invail despite i am sick today, i still hang on to go round even though my body couldnt take it anymore, my head was spinning but all my mind was to help him. I was so upset that today i couldnt even help him with 50bucks that he needed....i feel that i am such a lousy gf. My heart ache when i know that he meeting the gal he loved more than me, but i nvr mention that to him cos i know i hv no rites to stop him from doing that.....How can i make he knows that ihe is so important to me and i love him so much...My heart aches whenever i saw him flare up at me whenever he had things associate with the gal...i dont like that but what cn i do,cos i am so deeply in love with him, so i bear all that and keep to myself....It hurt me to see him going through the path that i went when i was at the age of 18, i really hope i cn do my best to help him in whatever way i can even to bear with his hurting words..
