Golden dose FAIL

As the title suggests, I tried and failed to get the golden dose of my 7.5mg pen. I did it last month with no issues whatsoever, in face I struggled much more the first time round but this time the pen completely broke and the pusher would not move the medicine 😖 not sure what to do now, I’m ordering my next lot which should arrive on Monday but with Christmas approaching there will probably be delays - do I dare skip a dose at Christmas time?!?!
