To add on with the CBT post... I would recommend
Centre for Clinical Interventions (CCI) - Psychotherapy, Research, Training
I used this in therapy and while it did not work for me, I learnt some things that I use occasionally. However, this is good as it goes through module by module and gives really in depth details on what you might feel and what you should do.
My pdoc also recommended moodgym:
https://moodgym.anu.edu.au/welcome but I did not try it.
hoping you find something soon!
