Hi Leila,
What you are going through right now is the most stressful part. Once you have your surgery and start treatment, you actually feel 'better'. You are more able to focus on just what you have to do to get through each treatment and stage of treatment.
I remember wondering if I would ever get a good nights sleep again at the beginning of it all! Things that helped me were to focus just on what I could do to help myself through each bit. The practical stuff like making sure I had as much sorted at home as possible, my gear for hospital and afterwards. I also went for a walk each day. This cleared my head and helped me to cope.
It doesn't hurt to have a few nice pamper moments in between everything too! It does get easier and you will find that you cope. Just be flexible, especially with work and family. People will want to help so don't be afraid to reach out when you need to. You don't have to go through this alone.
