Hi there and hope your doing well. Yes indeed its challenging to you. Just take it slow. Having an errand and your not feeling well its so stressful. But what can we do, need to accomplish it. I feel you too.. So sad but we have responsibilities in life. Just take it slow. And next time if you cannot accomplish your errands its ok to pause for awhile. And don't hesitate to ask help for someone. Stay hydrated, vitamins and enough rest to recharge your body. Stay healthy always and health comes first.
