I recently got caught up in a policy change on the Scottish NHS.
Basically a funding acquisition change, that requires another step PRIOR to referral to the GIC and thus getting on the waiting list.
I had been on the waiting list for 4 months, only to receive a phonecall to be told "Ehm...sorry, we have to take you off the list...yeah you now need to go and see this psych for a few months before you can be put back on the list...yes you will need to go back to the start of the waiting list...no I don't hate you...why are you crying?"
Suuuuuuuuucks, but I guess it's the price you pay for getting it all for free

My Psych did mention that there are hidden "Urgent" referrals that can by made in extreme circumstances, and that my situation may warrant that, the Urgent waiting list should be at least half the length of the standard one.
So maybe it's worth investigating if there is one/if you could get on the Urgent list in England?
