Anyway after completing my CPL I'm meant to be going and doing Instrument work to finish of my qualification/training,
This doesn't sound like YOU are I control here...
Finish off your basic CPL or you really do have nothing to show for your money... you are so close now. Do this, take a small break and re-assess. Don't throw money at IFR as it's more difficult and dry and will certainly put you off more than what you are doing now.
Difficult situation and completely understandable.
If it is the big "D," things may improve after you get some assistance and you may rekindle your love of the skies.
