Do things ever get better?

First let me start by saying.. I know thing can be so much worse in my life and I am very lucky to have an amazing mother. But at age 15 I lost my gradfather then my mom got breast cancer at 17and for the pastt 5 years she lost her breast went through chemo and has had 15 reconstructive surgeries. When I was 19 my father committed suicide leaving her to put my two brothe and i thru college and pay back all my father debts. Which now makes her 80 thousand dollars in debt from just that. (Because he killed himself all insurance money is negated). I guess what I'm trying to say is everytime I think things couldn't get worse they do. My boyfriend of 3 years had sex with both of my best friends and treats me like I'm the scum of the earth. I don't have a hometown anymore I live at my college and spend all my time alone because I have no car my mom moved out of our hometown, when we all went off to school, for a better job. She works all the time just to make sure were okay.. so, does it ever get better? I mean all I want is to not have to worry about money (but that's not an option when your a college student) I'm not trying to play the "poor me" victum but due to me moving away and my boyfriend & friends betraying me.. I have noone to talk to. I know things can only get better if I make them better but I have been trying so so long.. and its not :) so I thought I would write this and see what people have to say.. thankyou (excuse my grammer I know its horrible)
