Do you have any feedback about what is going wrong for you? That is probably the most important constructive thing you can have in your position. Ideally that will be from a clinical supervisor who knows you well, but if you don't have that it may be worth seeking that externally (or even paying for it) from someone who regularly hires for AP posts, IAPT supervisor or involved with PWP selection.
Also, I would be sceptical about any generic advice from people who don't know you, or well meaning platititudes from nice people. That may be helpful in making you feel better in the very short term, but in terms of moving forward, growing and developing far less useful
