My dad has stage 4 cancer oesophagus cancer, he lives alone and things are getting a bit tough right now. Although he is mobile, emotionally he struggling to be alone due to regurgitating, especially at night. He has been in hospital the last few days and I've been up there everyday, I'm exhausted mentally and emotionally. I'm not sure how long he has, but he can't keep water or anything down, so he will need a stent and then a course of radiotherapy to help improve quality. I work in a school so have 10 weeks left maybe I til summer. Can I get my doctor to sign me off? I'm not going in this week, but guessing I can self certify or just take it as compassionate leave.
