It's understandable that you would not feel love towards your family from hearing what you have been through and continue to go through. I am so sorry to hear that your family has treated you so bad. I really hope that you have someone, such as a therapist or counselor that you can talk to about the things you've been though. If you don't/can't get help in that way, I would recommend that you try journaling, or if you're not good at writing you could try drawing or painting or something like that. Some way to express and get out your feelings.
