PFNM - it is fixable, honestly.
Try this website - it has some self-help tips on NLP (therefore free) and you might be able to make some use of it.
Once you are feeling better about yourself, you will feel more able to cope with the situation with your daughter and you will be able to teach her how to deal with any negativity IF NECESSARY - remember, she might not react in the same way you did, but she will if she learns it from you.
Best of luck - keep posting whenever you need more support/ help!
