Fear of needles is common and called Trypanophobia. It can be improved by gradual exposure (starting with thinking about needles, then seeing pictures, then being near them), deep breathing, and relaxation techniques during procedures. If it is severe or affecting your health, therapy like Cognitive Behavioral Therapy is very effective and can help you overcome this fear step by step.

Your symptoms sound like Obsessive-Compulsive Disorder, where repeated thoughts and cleaning habits take a lot of time. Try to slowly reduce bathing time step-by-step (for example, cut 5?10 minutes every few days), avoid repeating rituals, and practice relaxation or breathing exercises when anxiety comes. It?s best to consult a psychiatrist or psychologist for proper guidance and support.
