It may be that you simply need to improve your sleep hygiene behaviours, such as going to bed at the same time each night or ensuring your mobile phone is not in the same room. Using a sleep, meditation and relaxing app like Calm will help and here is useful advice from the NHS on How to get to sleep.

However, if you are not sleeping at all and this pattern has persisted for some days/weeks, this could be a sign of severe anxiety or depression and we recommend that you contact your GP urgently to book an appointment. This link will take you to Doc Ready, which helps you prepare a template of questions to ask your Doctor, which you might forget if you are tired or feeling stressed.
