I've been living with my boyfriend and his parents for the past 2 months. I am 19 and my health has always been absolutely perfect, I haven't even had a cold for almost a decade. However, for the last month or more, I've constantly been getting ill. I've had one cold after the other with only a few days in between each one, so far I've had about 4. Each time I am congested and have swollen tonsils and lymph nodes, 1-2 times I think I had a UTI, and this time I have conjunctivitis. It is so incredibly painful. Moving my eye or even blinking makes it feel like I've been punched in the eye.
I can't inforce any extra hygiene practices since I am a guest here. I can't even see a GP because I can't register since I need proof of address and I don't actually live here, only temporarily. What do I do?
