What will i do if i have a child and no one will love me?

Not clear: I'm not sure if you're considering having a baby, are already pregnant, or already have the child. At 18 you're very young to get pregnant -- this is a major change in life, and it's rare that someone is ready by that age to become a parent. It's possible with a lot of support around you. Might be a good idea to go over options and possible consequences, with a therapist or counselor.
