Sadness, I hope you have alanon available to you asthe right meeting could really be a lifesaver for you right now. One thing for certain is that your parents emotional unavailability has nothing at all to do with your lovability! Having a baby does not automatically turn a selfish, self-absorbed addict into a thoughtful, caring, giving, nuturing human being. Nope, doesn't happen that way.
Please look into some living arrangements through school, tuition assistance, roommate, etc. Save as much money as you possibly can right now.
