Well my friend, I’m a lot younger than you, but with your hours, I would stick at it in some shape or form.
I don’t know if you have built these hours for pleasure or with a vocational goal in mind, but you are well ahead of most of those still to complete or start their CPL.
If I were you I would take some time out and do your ATPL exams. By the time you get those out of the way, things have got to be getting better (fingers crossed and all that!!!).
Ditch the IMC for the moment; your CPL will give you all the additional experience to complete it if you are even partly into an IMC course. Just do the odd hour to keep current then go for it.
There is a load of doom and gloom here, but has the populous stopped flying?….NO!
It’s a bloody expensive road to follow, but you are a long way down it, what’s a few more grand to get you to CPL with maybe an FIR bolted on?
Your money,…your call.
Good luck
