Insomnia

Got the worst insomnia 6 weeks in. Have hardly slept. Fall asleep ok and then awake from 2am- 6am. It is so debilitating. Is there anything I can do? Almost getting scared to go to bed for fear of being awake all night. Just so drained 😢 Is anyone else in the same boat? I used to have some night nurse when I couldn’t sleep to help but don’t think I can have this now.
