I think I screwed up, because I feel real bad about this. What else could I have done?

My daughter, she is now 8, believed in Santa Claus,until now. I had to tell her. Let me further explain...My husband and I have 3 kids. Money is tight being that he is the only one working.I can't work because i have medical problems. Anyway, there was one thing my daughter wanted real bad...however it was about $200. We managed to get it for her. The thing is..on Dec 24. is when we have Christmas with my mom. Here we let the kids open the presents from us as well as my mom. On Christmas, they open the presents from Santa.She received her $200 gift on christmas eve. The only presents we had left were some that a friend gave us to give to her. We didn't have any more money to spend on her. We didn't tell her about the presents from the friend. What we did was put them under the tree on Christmas and said they were from Santa. When she woke up and saw them, she started crying. It wasn't anything she asked for or wanted. She thought she had done something bad and that is why santa didn't give her anything she asked for. We then told her the truth. Santa was not real. We told her about the money situation and that we could just afford the present that she was really begging for, but that was all we could spend on her because it would not be fair to the other kids if she got more then they did. She then started crying again, saying we had been lying to her for so long and she just walked off. She pretty much avoided us all day. What else could I have done? I guess I could have kept lying and said santa doesn't have much time to spend on each kid so everybody doesn't always get what they want--or something like that. But I told her the truth.Was I wrong? She is only 8. I did make sure I told her those presents she got were not because she was bad, that is just all we had to give her.
