Daughter Has Seperation Anxiety

I'm a SAHM and I need tips on how to help my daughter get over her separation anxiety. It's really bad. I can't do anything or even go into the next room (she can still see me) without her screaming and crying. I've tried to get other family members to watch her for a bit, but they just don't want to deal with it. How am I going to fix this situation. Shes almost 2 and I can't leave her with anyone, not even my husband.
