I remember those feelings well,I had surgery 2days before Xmas 2016. It was an awful time . I had a 13 and 14 year old at the time and was so worried about the future. I became quite depressed ,fast forward to now and thankfully I am cancer free and life has gone on ,at the time it doesn’t feel like it will.i was 40 when diagnosed,I understand how your feeling but know things will get better.like the other ladies said it is better to take each day at a time because I felt like the process takes time even though I was very impatient at time. Also I really benefited from meditation,although I know it’s different for everyone.
