OCD refers to obsessive compulsive thoughts and behaviour. These can include obsessive thoughts around four types of vulnerabilities which are: 1) health and illness, 2) danger, 3) poverty and 4) losing control.  Specifically, we can think obsessively about sex, death, relationships and contamination, amongst others. We may behave compulsively by cleaning, checking and double-checking, repeatedly asking our partner the same question, for example. We also tend to avoid certain situations which makes us feel particularly anxious. On a physical level, it is common to experience a tightness in our chests, shallow breathing, sweaty palms, palpitations, dizziness or brain fog when in the grips of obsessive and compulsive thoughts and behaviours. We may also generally feel low in mood, lonely, empty and tired because of our condition.
