Literally sitting here in tears

I suffer from anxiety... And my current med is ativan. At first it worked great .but its made my appetite decrease dramatically. Not to mention I can't eat alone BC I think all food is going to kill me (i have food allergies) Like I've lost 10 lbs. Which for me isn't good. My thyroid Dr and I talked and he thinks I need to go on xanex. Idk how to bring this IP to my Dr. Just the thought sends me into a panick.. What if she thinks I'm after drugs.. What if this or that...anyways. I'm alone about 95% of the time w. My 5 month old. Which isn't helping. . . idk what to do anymore. I want to eat I do but the thought terrifies me BC I'm afraid I'm going to die...
