I'm sorry things did not work out with your boyfriend. I know it is hard now, but it may be for the best. You want to be with someone who can love you for you, good and bad. You want someone who, if something goes wrong, they don't turn cold on you or turn their back. And you want to be with someone that good or bad, you will be able to stand with them through their hard times.
As Trippin2.0 said, it will be better for you to start a relationship when you are a whole person. Don't worry so much about relationships right now. Work on yourself so you can be the best you that you can be. And do it for yourself, not anyone else.
