And I'm a brave soul.
Crutches, for me, were horrible. For short- or long-distance. Perhaps it was my lousy balance to begin with (good on you for recognizing that in yourself), or perhaps it was just a fundamental dislike of intentionally trying to stabilize on a very unstable tripod. With a huge hunk of plaster on one leg.
No...you're not being overly cautious. And please tell the people who have unhelpful opinions about this to hush. If they haven't experienced what you have, then they should hush.
Please consider the alternatives...for me, a wheelchair, then a walker/zimmer, then a cane. Worked.
And do consult your OS and PT; they can advise you well about how you'll ambulate the best.
Hang in there, love...you're doing well!
