I know how you feel my wife was diagnosed with colon cancer on 2/7/2020 was initially told was isolated but ct scan 10 days later showed stage 4 spread to kidneys liver and lungs they gave her a operation to put stoma bag in then told us would be followed up by chemo they did say it wasn't curable but may give her more time then told us chemo wasn't an option and sadly my wife passed away on 23/8/2020 so only a short time after diagnoses just like you I feel i was robbed of a beautiful woman only 54 years old and she was robbed of her life my 2 boys are devastated they are 16 and 17 but she was there world it's 6 weeks now and I still wake up looking for my wife even at times calling to her it's habit they say time gets easier well I'm not sure about that at the moment the slightest thing still causes me to break down in tears I still whisper denises name all day long asking why this happened to us but it's not for us to question only god knows why I'm sure your sister is with all the time at your side and watching over you all 

take care of yourself that's what she would really want
