Parenting is difficult. Parenting during a personal crises is overwhelming at best, and sometimes, impossible. You did the right thing in taking your daughter to your parents home.

In the city where I live, there's a 24/7 crisis daycare. Parents can utilize the center, on a drop in basis, up to 72 hours. Perhaps there's one in your city too.

If you haven't (and you may have already) communicated to your support system (sounds like you have your parents at least) your need for additional help, there's no time like the present. You needn't go into great detail, just let them know that for now, additional help with short notice daycare is one of the ways they can really help you out. It'll be good for your little miss, and good for you too.

We all need to have a crisis plan that takes care of the ones we love most, and allows us to have space and time, when the many burdens of being bipolar, overwhelm us.

You are a good parent. That's obvious because you feel so badly about "flipping out" in front of your daughter. This is a dark time for you, we all have them, and can relate to the pain you're going through. As a wise man once said "This too, will pass away". Hang in there, plan for the good times and bad, and utilize every resource at your disposal. I wish the best for you and your daughter. Remember, the love you have for your darling daughter will never leave you, and no one can take that from you, ever. Be kind to yourself, forgive yourself, and after a time, the light will come back.
