I have a younger sister who has always been a constant source of worry to me as she is 6 and has always been a sickly child. This year, she seemed to be getting better with her hygiene and I agreed with my mum that I would take her to school on some weekdays... Normally I don't like being alone with her (I know it sounds horrible, but she makes me so anxious) now a few days ago she got ill and as I've just started therapy I was encouraged to stay calm and managed to even though I know she got sick. I convinced myself I would not catch it as it only lasted about 12 hours and I have a much better immune system than her. I went near her, talking to her. But 24 hrs later she felt unwell again.... And when I woke up this morning my dad informed me she has all the symptoms of norovirus, literally uncontrollably. I have cancelled all my plans and desperately want to leave the house but I am too scared of being out in the street and getting ill myself... There is nowhere close enough that I feel safe walking to I am downstairs whilst she is upstairs and I haven't seen her all morning my mum promised she won't bring her down but I am beside myself. I haven't eaten since yesterday morning now and my stomach hurts so much. I am literally forcing myself not to cry. I feel so trapped. I would be so grateful to anyone who could give advice or support... I am sorry for the long post or if its not appropriate
