I am currently learning by trial, more often error, how to cope with vertigo
@paladrina, I know the feeling
What I have learnt, both 20 years ago when diagnosed with acute benign postural/positional vertigo and from the discussion you have started, is that, like the common cold, there are many forms of vertigo.
Looking back at how my one and only notable episode started, I noted tiredness and anxiety were the key drivers. With overtones of maintaining balance thrown in.
For me, if I now begin to note tiredness and anxiety, possibly coupled with light-headedness, I divert to something else. This may be a "cup of tea and a sit-down", for example.
As
@Shells says above, ”Tranquila, Peregrina, tranquila!,” (quiet, peaceful)
A tool I have found extremely helpful (and mentioned above) is a satisfactory pair of walking polls.
First, the locking mechanism must work.
From my experience, the most unsatisfactory is where the pole sections are rotated one way to lock and the other way to unlock.
In my experience an external lever, regulated in tightness by a thumb and finger sized knob, works best.
For air travel, I have a pack liner that doubles as a carry bag with handle. The empty pack goes into the now carry bag, then the poles (demounted as suits) followed by soft items between carry bag and pack, with larger items inside the pack - or however it works for you. The entire package is checked in (not including expensive, low-price airlines).
So I wish you kia kaha, kia māia, kia mana'wa'nui (take care, be strong patient and confident).
