Being left behind

Recently me and my boyfriend had broken up. It has felt awful and like I had no one and it still feels that way. I have homecoming in A few weeks and i had planned on going to homecoming with him and the fact that we both live within the foster care system made is so we cant go together. I want him to have a normal life and to have a normal dance and i get it. I feel that with all thats going on in my life this is the hardest to deal with. I feel completely alone right now. The only person i want to cry to about this is the person who abandoned me and cheated on me. I know that I have people who care about me and that's what keeps me going on somedays. I know that compared to a lot of kids my life seems easy(and at points it is) but my life isn't the best. I know that this pain is part of the normal teen experience and all, but he said he wouldn't leave me and he did and it hurts alot
