I've tried hypnotherapy before . I know it's not the kind you meant but in my own experience it can help with those kind of things . I saw a hypnotherapist when I was younger . It worked wonders but I didn't go back . The positive effects of that one session lasted about a year . I want to go again . It's a bit pricey . I've tried the free recorded hypnotherapy on YouTube and it didn't work for me , had to be face to face. Sorry if this is not helpful at all
