problem with bf

Everytime something bothers me, doesnt go my way or upsets me i go to my bf to cheer me up/make meess stress since i do that gor him. But he knows whats stressing me is school/job so its not a minor thing. He just brushes it off. But i am always there for him if he thinks he failed a test there i am comforting him yet he brush off my problems like they mean nothing. I tell him to just care more but it doesnt. Ive stopped telling him how i feel because he doesnt understand or even act it. It hurts my feelings so much. I just feel like im an inconveinence
