I work with many clients who have struggled with anxiety due to stressful experiences, including work and exam anxiety, panic, and after trauma.
I also treat those who have phobias to a range of triggers (e.g. heights, blood, dogs) as well as obsessive-compulsive disorder, which is when a series of thoughts and/or behaviours become distressing and distracting. Clients I have worked with include obsessive thoughts about death and counting in multiples, and compulsive hand-washing, germs, checking doors, and hoarding.
