Sorry to hear you're feeling like this, although I admire your proactive approach to a problem I think many face at some point or another! I have plenty of experience of using CBT to work through exactly what's making you feel stuck, combining it with techniques of mindfulness, meditation and visualisation to move you forward really positively. The answers are all in your head, we just have to get to them!
I have a special Nappy Valley rate at the moment for up to 3 individuals (just posted today), with £15 off every visit with me. https://www.anna-jordan.com/
I have private clinics in Soho and Harley Street but I live in Balham so I'm happy to make home visits in SW.
Whatever option you choose I wish you luck!
