From what you described, it's essential to note that I can't diagnose any mental health condition, including OCD, as that requires a thorough evaluation by a qualified mental health professional.
However, engaging in repetitive and harmful behaviors, such as jamming sharp objects under your fingernails, could be a sign of a psychological or emotional struggle. It may indicate a self-harming behavior or be a way of coping with stress, anxiety, or other underlying issues.
OCD typically involves experiencing intrusive, distressing thoughts and engaging in compulsive behaviors to alleviate anxiety or prevent perceived harm. While repetitive behaviors are one aspect of OCD, it's not the only symptom, and OCD can manifest in various ways.
If you are concerned about your behavior and its impact on your well-being, it is crucial to seek help from a mental health professional. They can provide an accurate assessment, diagnosis, and appropriate support or treatment options tailored to your specific needs.
It's essential to prioritize your mental health and well-being, and seeking professional help can be a significant step in understanding and addressing any challenges you may be facing. Remember, there is no shame in seeking help, and many effective treatments are available to assist individuals in managing their mental health concerns.
