Hmmm... If you feel that badly about yourself, then that partly explains why you're so vulnerable to what Twunty says: he tells you bad things about yourself that you already partly believe. He makes your worst fears feel true. :(
Well, here's another perspective...
You are a loving and sweet person. Your love for your DD spills out all over this thread. :) Your natural instinct to be nice is so strong that you try to be nice even to people who are treating you badly.
You are kind. Even here on your own thread, when you are utterly miserable, if someone else mentions their own bad experience, you are the first to say something kind to make them feel better.
You are funny. Your sense of humour is subtle not raucous, and it's very powerful - you manage to laugh even through your tears and you'll try to make other people smile whenever you can.
You are smart, thoughtful, perceptive and articulate. All through this thread, you have been grasping new ideas and making sense of them quickly. You express yourself clearly, even when you are trying to express very difficult and unfamiliar emotions.
You are a survivor. You have escaped a horrible, emotionally damaging relationship, and just a few months later, you are getting yourself back on your feet. You make the best of what you have, and just get on with things - even when you're feeling bad. A single room, a tatty car and almost no money... Well, they're just what you've managed to sort out so far - they're enough for this moment - and you'll sort out more when you're ready...
You're a provider. Your DD has all she needs. She's little: what she needs most is her mummy's love, and she's got it :) You have your priorities absolutely right: you're dedicated to keeping her safe and happy right now, and that's exactly what she needs. When she starts needing other things, in years to come (like pocket money and toys) you will sort those things out too.
You are far stronger than you think you are. Even in the middle of your grief (and during pregnancy, when many of us just slob!) you are keeping it together for your DD. And what's more, you have got yourself a place at college - which is a real achievement, especially under the circumstances. :)
So what if your head is a mess and you're a bit chaotic and self absorbed at the moment?! All the rest of us have faults; you've got to have your share too! 
Give yourself a break, Make. You don't need to be perfect... And you are perfectly good enough!
