Using this website instead of talking out your fears with family and friends is a good idea - the reassurances you get here are based on experience, not hope (although that’s a good thing to have too!) and many people in your situation find that more time than is entirely sane is taken up with comforting others (who don’t have cancer). Your treatment has started which is good. Your next stages will soon be clearer too. Knowing what you have to do short term is usually really helpful - it occupies your mind and keeps you busy. But as @Nefertari says, don’t discount the value of some counselling later on. The mental impact of cancer (society’s bogeyman), its treatments and what it may mean long term can be significant - intelligent people find it hard to deal with. The more you dwell on it by yourself, the more problems you can envisage - including all those that won’t happen! Try to take one day at a time, catch your breath and remember that the devil you know, understand and can come to terms with is not so scary. Best wishes.
