It sounds like you may be experiencing some obsessive-compulsive tendencies related to handwashing and cleanliness. If these thoughts and behaviors are causing significant distress or interfering with your daily life, it's essential to seek advice from a qualified mental health professional.
That being said, OCD can manifest in various ways, and the obsessions and compulsions can differ from person to person. Your need to wash the tap and door handle after washing your hands might be a ritual or compulsion driven by your obsessions about contamination. It is crucial to understand that OCD often involves irrational thoughts and behaviors.
When dealing with OCD, it's not uncommon for individuals to engage in rituals or compulsions to reduce their anxiety and distress. However, these behaviors can reinforce the OCD cycle, making it difficult to break free from the disorder.
Seeking therapy, such as cognitive-behavioral therapy (CBT) or exposure and response prevention (ERP), can be beneficial in managing OCD. A mental health professional can help you identify triggers, challenge irrational beliefs, and gradually reduce the compulsive behaviors.
While I can provide some general advice, it's essential to consult a mental health professional who can assess your specific situation and provide personalized guidance. They can offer strategies to cope with OCD and help you work towards a healthier and more balanced approach to managing your thoughts and behaviors.
