I went away last Monday within the UK, 5 hour train away and was meant to return on Thursday. However I came down with a really chesty productive cough and have been feeling generally rubbish. I had lateral flows with me for work and have now done 5 all negative and whilst up here have had a negative PCR. I have extended my stay twice first to Saturday then again on Saturday until today. I'm still feeling a bit rubbish but lemsip flu plus is helping and I'm a lot better except the cough is bad and is happening a lot. I'm feeling so panicky at the thought of being on a train coughing this much but I need to get home to my very little boys (both under two) and I'm going to struggle to afford to stay here any longer accommodation wise. I don't have a car and no one that can pick me up from this location. AIBU to get the train? If I wear a double mask and try my hardest (appreciate it's our of my hands overall) to pick a quiet seat? I am sure it isn't covid after so many negative tests but appreciate other passengers won't know that.
