It sounds like you may be experiencing a condition known as "paranoia." Paranoia is characterized by irrational or unfounded fears and suspicions about the intentions of others, and it can sometimes manifest as a persistent belief that someone is in your house or watching you, even when there is no evidence to support this idea.
It's essential to recognize that you are not alone in feeling this way, as many people may experience feelings of fear or paranoia at some point in their lives. However, if it is becoming a daily and distressing occurrence, it's crucial to address it for your well-being.
There could be various reasons why you might be experiencing these feelings of paranoia, ranging from anxiety disorders to stress, trauma, or even certain medical conditions. If you find that these fears are interfering with your daily life or causing you significant distress, it's essential to seek professional help.
Consider reaching out to a mental health professional, such as a psychologist or psychiatrist, who can provide a thorough evaluation and offer appropriate guidance or treatment options. They can help you understand the root cause of your fears and work with you on coping strategies or treatments to alleviate them.
In the meantime, it might also be helpful to talk to someone you trust about your feelings, as expressing your fears can sometimes provide some relief. Engaging in relaxation techniques, such as deep breathing, meditation, or mindfulness exercises, can also be beneficial in managing anxiety and fear.
Remember that seeking help is a sign of strength, and you don't have to go through this alone. There are resources available to support you in overcoming these challenges and regaining a sense of security and peace of mind.
