All support for mental health has ceased in most if not all areas as if is not seen as "essential medical need" including all support workers that were helping people to get essential needs met. These gaps are not being filled, by anyone. Mental health charities she may have relied upon will be closed as well.
No one here knows what the friend is going through. She could have been under mental health workers who are now indefinitely gone. She could have had a support worker who is also indefinitely gone.
Try a bit of compassion, asking for help when suffering, genuinely suffering with the mental illness that is anxiety is extremely difficult. And no going shopping isn't like usual shopping. I can barely cope going outside because of my mental health in recent days.
Does she have anyone else she can ask? Is the question you need to be asking her, gently, and you need to explain, gently your situation as well, see if you can find someone more suitable in your lives to help her. DO NOT go with how minor her anxiety is, or get a grip type of conversation. This is not a time to be kicking a vulnerable person when they are down.
Think of the anxiety everyone is talking about having because life has changed. Now imagine living with that level of anxiety every single day of your life and multiply it, many many times.
And before anyone asks, people with physical disabilities have found their support stopped too. The advice from Drs and social services is not to bother them but to get "friends and family" to help, even, yes even, if that means being abused because they are not allowed to and there is no one else.
