So my family have asked me to get help

@LisaO If that's all they're concerned with, I think you're rocking it. This stuff is going to change you.   Do you think there's other things they're not saying  though, as lack of planning can be a symptom of PTSD but wouldn't stand alone?  It does sound from your description that's not the case.  However, if it stops the worry, maybe you could see someone - but someone who is experienced with breast cancer and how it affects people.  And I would go one step further and suggest that at the very least, your husband should also see that person so that there can be some reconciliation between your normal and the family's expectations.  By the way, I am 54, love my job although I'm on extended leave at the moment (did some fun work for them yesterday, anyway - don't tell the Super people) and I don't think about retirement as seriously as I should.  It's something vague in the future.  The same goes for plans more than 1 year ahead.  This is pre-cancer non-planning.  Now, just over 3 months from diagnosis, and still undergoing treatment, I'm lucky if I can plan for a month.
