Thanks for the advice guys.
The regrets stem mostly from things/decisions I have taken over the last few years when I was sober/hungover rather than drunk. Although I suspect that whilst I was drinking I probably wasn't thinking straight about anything, at any time.
I need to leave all this failure behind but I've lost so much money and time and the world is in such a mess that I don't know that I can make things better this time.
I have no desire to drink which would have been the normal response a year ago, but I can't seem to mentally deal with what has happened to me.
Regret is useless, but it keeps running me over.
