Hi ToeJam, the IAPT sounds like a really positive move!! And the CBT should be a little more "structured" for you, so maybe that will be a bit easier in getting across how you're feeling, it may in some ways be a bit less "intense"?? I'd say go for it!!
Plenty of really good backing out there for how CBT can help some people with depression, but just take things at your own pace with it (shouldn't be any pressure remember!!) and bit by bit...........
Really good that your G.P is so invested in supporting you so much with what you're going through........so maybe a possible that if the urges come on/things are hard you WILL contact him in between times???!!!
