Timid is a natural feeling. You'll gain confidence.
It's been 10-1/2 months for me.
With the nice weather, I would just jump on the bike instead of walking.
I rode 70 miles on July 31. Not bad for a 65 yo with emphysema & hybrid.
Last Sat. I walked 3+ miles. My calf muscle was actually sore the next day, simply because I hadn't been walking much.
You NEED to WALK! When convenient, exaggerate your stride and make that ankle work.

My recommendation-
Even if using the crutches, try to stride a bit more than comfortable. For me, IF I didn't end up hurting some, I didn't have improvement.
Work into it slowly, so you KNOW you have recovered the next day.
Once you know you recover the next day, it's a matter of the more pain, the more gain.

Your cycling miles should increase quite rapidly. You simply don't have to bend the joints (under load) as much.
