"I have been very tired for several months?"

It is important to prioritize good sleep hygiene to improve your quality of sleep. This includes avoiding screens before bedtime, maintaining a consistent wake-up time, using the bedroom only for sleep and intimacy, avoiding naps during the day, and avoiding stimulants like coffee in the afternoon. Keeping a worry journal can also help to clear your mind before bedtime. It may take some time to see improvements, but with patience and consistency, you can work towards better sleep. If the situation becomes unmanageable or you are unable to carry out normal activities, it is important to seek help from a doctor.
