If you are concerned about your feelings and behaviors, I strongly recommend consulting with a qualified mental health professional for a proper evaluation.
Having strong aversions to certain textures or sensations, such as oily or greasy substances, is not necessarily a sign of OCD (Obsessive-Compulsive Disorder) on its own. OCD is a complex mental health condition characterized by intrusive and distressing thoughts (obsessions) and repetitive behaviors or mental acts (compulsions) performed to alleviate the anxiety caused by those obsessions.
However, if these aversions significantly interfere with your daily life, cause distress, or are accompanied by other symptoms like intrusive thoughts or rituals, it may be worth discussing with a mental health professional. They can help you determine whether it is related to OCD or another anxiety-related disorder or whether it is simply a personal preference or sensitivity to certain textures.
Remember, seeking guidance from a mental health expert is the best way to receive an accurate diagnosis and appropriate support or treatment if necessary.
