Bipolar, and experiencing a mixed state?

[Cindy]

I was diagnosed with bipolar a couple of years ago. around that time my life was pretty hectic, I was self medicating with alcohol and drugs. Soon after I became clean, met my husband and had a child. Everything was fine for two years, I experienced a few depressive episodes but didn't think much of it, Life was actually looking up, and for once I felt "normal", and started to believe that I was misdiagnosed. Well, now I've been having what seems to be a mixed state. Its starting to hurt my relationship with my husband, and I want to seek treatment for it but I am worried that if I tell my doctor ( i have a new one, and moved to a new city so he doesnt really know my past history) whats going on I might lose my daughter. I'm not really sure what to do, because I couldnt bare the thought of losing her. She's my world, my everything, i'd be completly devastated if her lost her over my disorder. So my question would be is it possible for them to take her away? Believe me I know that I'm being paranoid right now, but I do feel as if I need to talk to my doctor about it so I can be medicated and seek therapy for the sake of myself & family. And to answer a few questions that might be asked I am not abusive towards her, I always push myself to do and be the best parent I can be. I am also not having any hallucinations. as for delusions I've never believed to be a higher power, or anything nutty like that. Thanks
