Sorry you’re having rough time.
Loads of people here (me included, by a well-known meno consultant) have been told to cut patches in half.
People have different preferences Personally I find diagonal best to be sure equal pieces - but some people don’t like the pointy bits.
It can be a bit fiddly, edges not quite as sticky etc - sometimes I had to replace the bits more often if they came off.
But it’s definitely common advice/practice for lesser doses.
All that said, there are a lot more knowledgeable/ experienced people here so I’m sure someone will be along soon.
Good luck x
