'Why do you climb?  Sometimes our motivations, which fuel us at the start  of a 
climbing career, can return to haunt  us later on.  For example many climbers feel that they are overcoming  something or proving something by 
climbing,  which can be very motivating and empowering initially, but unless you  are super talented, there will come a point where you can no longer  overcome or prove something simply because you cant climb any harder,  and the weight of expectation then becomes an double edged sword.
Clinical psychologists have a long history of working with fears and  phobias and there is good research evidence to help you match up  specific approaches to specific fears.  For example, behavioral  approaches such as exposing yourself to the thing that frightens you (eg  practising falling off if that's what terrifies you) in incremental  stages will help you recondition yourself.   However, in practice many people find that going straight into exposure  can be too difficult.' 
Cognitive behavioral techniques (CBT)- Which aim to tackle unhelpful  thoughts and undermine the evidence for them through behavioral  experiments, can also be helpful and have been proven successful.  For  example, perhaps your self talk goes along the lines of “this is hard,  this is too hard, I can never do overhangs” etc etc, then the approach  would be to gather evidence to the contrary of this, eg record times  when you have climbed harder and successfully completed overhangs.  You  would then spend time practicing more helpful self talk so that you can  access this in your anxiety-provoking 
climbing  situations.   
Neurolinguistic programming (NLP)- Which also aims to change unhelpful patterns of thinking, where you may  use anchoring techniques in different sensory modalities to replace  anxiety with relaxation, eg place a sticker on the back of your hand for  you to look at when you feel anxious, which you have previously looked  at whilst practicing being relaxed.
Mindfulness techniques- Are essentially meditative, but don't require  sitting in a quiet place and chanting.  Rather, we allow ourselves to be  fully present in the moment, connecting with all our sensory  experiences.  This can be particularly helpful when 
climbing  as attention to all elements of the sensory experience can improve  performance.  For example, noticing areas of tension and relaxation in  our body can ensure the right amount of force is used at the right time  and place; paying close visual attention to the rock in front of us can  help us spot hidden variations which allow for better positioning, and  so on.
