Oh, love, you poor thing.
Firstly, you did the right thing asking for emergency help when you knew you needed it for the protection of your Dd.
She is safe, you have met the foster carer and know her to be nice.
Now look after yourself. Get rid of all alcohol and any other temptation to drown your sorrows or self medicate.
Give yourself a sense of achievement, a little decorating - but no home needs pristine paintwork, so do not put pressure on yourself.
Eat as well as you can, and make sure you take your daily walk, brisk, breathe in lots of fresh air and look at the horizon.
Would it help to write a little diary for your dd? A letter each day, telling her what a darling she is and in doing so reminding yourself that you are not a bad mother, you are ill?
2 year olds can be very clingy, and is it possible that the house move disconcerted her a bit?
Yes, call your social worker, and ask if there are any other avenues that you can explore to hep your mental health at this time.
You are having a very bad time in difficult circumstances, you haven't ruined everything.
