You already have the insight into your problem. You state it in the first sentence. Sounds like you have some depression from your situation, having no life and no one to talk to. The symptoms you describe are those of anxiety and depression. You really need to make time for you and your daughter. Make plans to do something, and follow through. Start an activity that is fun for you and that your daughter can participate in, if possible. But, you also have to find time just for yourself. You have to be at your best to raise your child.
You probably do need to talk to someone. It doesn't have to be a psychiatrist, just someone you trust; a good friend, an old teacher, coach, your pastor, whoever. You'll be surprised how much just talking can help. But, if this doesn't do it, you do need to seek professional help. Don't let it get to the point that you do end up in a hospital.
Good luck.
