It can be difficult to determine an exact diagnosis. Sometimes individuals exhibit symptoms associated with multiple diagnoses but they don’t technically match all of the criteria for any one particular condition. Based on the details of your letter, I would tend to agree with the other mental health professionals who believe that you may have a mood disorder, possibly bipolar disorder. You experience deep depressions and periods of productivity. Cycling between these extremes is an indicator of bipolar disorder.
OCD may also be a possibility. You worry about being accused of crime that you did not commit. Some individuals with OCD have similar fears. A common fear among some individuals with OCD is that they have accidentally hit someone with their car. For individuals with this particular obsession, they can become so afraid of accidentally harming another individual that they are frightened to drive their car or leave their home. The underlying fear associated with this particular obsession is losing control. Please keep in mind that having only one symptom of OCD does not mean that you have an OCD.
You also experience paranoia. To know if this is a symptom of any one particular disorder I would need to know many more details about the paranoia. If paranoia is an everyday part of your life, then it may be indicative of a psychotic disorder such as schizophrenia. If it only happens on infrequent occasions, then there may be another explanation.
The visual and auditory hallucinations that you mentioned may be associated with sleep deprivation and not necessarily a symptom of a psychotic disorder, such as schizophrenia. Having visual and auditory hallucinations on the verge of sleep is a relatively common phenomenon. I would suggest speaking to your psychiatrist about this symptom to determine if he or she believes these are actual hallucinations or part of a normal sleep pattern. If these auditory and visual hallucinations are disruptive, you may want to have a sleep study done to explore the possibility of a sleep disorder.
It is difficult to know your precise diagnosis but what is clear is that you are struggling. You need help. Even if you were given an exact diagnosis, it would not cure your problems; you would still need help. In my opinion, searching for a diagnosis is an inefficient use of your time and energy. A better use of your time and effort is finding a competent mental health professional who can help you deal with your problems. Look for a mental health professional who has a successful track record of helping people with similar problems. Medication may help to stabilize your mood. Counseling can help you to deal with your depression. Counseling can also help you with your possible OCD or fear of losing control. I hope you’re able to find the help that you need. I wish you the best of luck.
