One of the most frequent bits of advice on this site, particularly to those who are coming to terms with a new diagnosis, is to take one step at a time. It's practical because it's easy to be overwhelmed. It's also sensible because the prospect of still having "treatment" (not necessarily invasive or unpleasant) years later may be much too hard to grasp when you are feeling very vulnerable. It's not a conspiracy, more a benign disinclination to emphasise the harder parts of what may need to be done. Bit like childbirth! So it's normal at this stage to feel betwixt and between. Better but not well. Treated but not done. Bad bits over but not back to normal.
So you start on working out the new normal, which is an important part of recovery (physical and mental). And you know how far you have come, so while doing more is a bit of a trial, you know you can do it. It's a long path, that's why you don't want to count how many steps you will need right at the start - a) you don't know and b) it's a hell of a lot more than you think you can manage.
And yet here you are, and you have done so much. So of course you can do a few more steps ......
It helps if other people also recognise the transition to the new normal and don't expect you to seamlessly resume normal service!! You need to retune all of you and it takes time. It may also take you somewhere good. Best wishes for the next stage, you can do it.
