No, it’s not a waste of time or money. If you are a home dweller because you work from home and have little reason to leave your home then, I would not see this as a problem. However, it seems as though the reason you won’t leave your home is because you are overly concerned about what people think of you. You also feel as though you’re being watched and that people are laughing at you. In the latter instance, the reasons you won’t leave your home may be indicative of paranoia, which is a significant mental health concern.
Paranoia is not a normal, everyday occurrence. It is associated with mental health disorders such as paranoid personality disorder. The main features of paranoid personality disorder include a pervasive pattern of distrust, suspiciousness of others and feelings of persecution. It is possible that you have paranoid personality disorder but only an in-person, in-depth mental health evaluation would provide that determination.
As I described above, the reason you won’t leave your home is what matters most. In your case, it seems as though it is paranoia that is keeping you confined to your home and thus may indicate the presence of a mental health disorder. It would be prudent to make an appointment with a mental health professional, report your symptoms and participate in the recommended treatment. Please take care.
