Yes it's very easy to know our had habits we inflict on ourselves like overthinking things, and far less easy to find a way to change. 🙄 CBT did give me skills to be able to see things clearer and also to help me slow down when the negative stuff started to spiral. It was 100% worth working on the CBT side of things. You definitely have nothing to lose, all positive steps forward will help. And of course the therapist will be there to work with you.
It does take some courage to seek therapy as we know we may be opening ourselves up for stuff we kind of prefer to keep hidden away, ( easier not to face things, that's me) so remember to tell yourself that you are doing a positive action, a kindness to yourself. Xx
