Symptoms such as nightmares and fear of sleeping alone may be related to ongoing anxiety, depression, or side effects of medication, and sometimes it takes time or adjustments to find the right treatment plan. The most important next step is to follow up with your psychiatrist, as your medicines or doses may need to be changed, adjusted, or slowly tapered and replaced. Do not stop or change them on your own. In addition to medicines, therapy (such as counselling or cognitive behavioural therapy) can be very helpful in managing fear, anxiety, and sleep problems. You can also try simple steps like maintaining a regular sleep routine, avoiding screens before bedtime, practising relaxation techniques (deep breathing, meditation), and keeping a calm sleep environment. If your symptoms are worsening or you feel very distressed, seek medical help promptly. With the right combination of treatment and support, your condition can improve.
