Hello, I'm 15 and I have recently discovered that my dad was diagnosed with terminal small cell lung cancer.

My dad has had lung cancer for 3 years and was initially diagnosed in 2015, however at the time, it was treatable. For two and a half years I did not know about his illness, he was his normal self, going to work, enjoying life and doing what he loved. However about 6 months ago I started to notice changes within my dad. Perhaps the most noticeable was his speech which has degenerated significantly as well as his movement, due to the cancer spreading to his cerebellum. I asked my mum about his condition but she did not tell me until 3 months ago when she sat me, my brother and my sister down to tell us. It was devastating, seeing him go from his intelligent, compassionate self to his current state. He is currently doing chemotherapy, which we hope will manage the cancer for a while, but unfortunately it is an aggressive mutator, meaning my dad's death is likely only going to be delayed for a few months, at most 1 or 2 years. I'm posting this because it seems the cancer has taken him already. He has given up fighting and has changed so much he seems like an entirely different person. I frequently reminisce about the time we shared together. Traveling through France in the summer holidays, playing music as we journeyed, exploring caves, visiting water parks and playing crazy golf. I remember him teaching me my first line of programming code and helping me pass my computing science course to achieve my Duke of Edinburgh award. I recently finished my National 5 exams, but instead of celebrating I have felt more miserable than I ever have before. Please share with me your words of wisdom and comfort in this difficult period of my life.
