what to do

Hi, im new here, only diagnosed a year ago,

im in a bit of a predicament, my asthma has been bad all weekend, (wheezing, a little breathless, tight and painful chest) so i went to see a nurse at my doctors yesterday, she gave me an extra inhaler (brown one) and another blue one as my previous had ran out. she said to take it and if i don't improve go to a and e, so i went to a and e this morning because the inhalers haven't really helped and they said i should go back to the clinic, so phoned up the clinic and cant get an appointment till 11 tomorrow, she said i could book into a and e but the wait would be a very long time ( says 4 hours average wait on the website and there were lots if people there), i picked up a leaflet for this emergency doctor after 6:30pm, where you phone up and they give you advice or send a doctor out etc. the problem is im not sure whet to do,

do i :

wait till tomorow and go to my doctors

go back to a and e

or wait till 6:30 and call this hepline?

thank you
