Please help my 9 month old always refuses bottle

I am writing this crying because I don't know what to do anymore. I start work soon and my little one started to refuse bottles (formula) since about a few months ago. I have tried different formulas, bought 20 different bottles and she still cries murder when I offer it to her. She refuses it. If anyone else gives it to her, she will not eat it. She can cry for hours but forget it even if she's hungry she WILL NOT take it. I can't express as don't have a lot of milk anymore supply has decreased. I need her to start taking formula from the bottle. She won't even take it from sippy cups. Does someone have any advice I really don't know what to do anymore and i am DRAINED! I have tried everything and nothing seems to work. All she wants is the boob. Please help
