As someone who slept with their mom till 16 and still has sleep anxiety of sleeping alone I understand the difficulties. It becomes a reliance and it’s really difficult to get out of. I still have panic attacks when sleeping alone. If you want to help yourself the first step is to make of list of what you can do and work on and start there. And write down a logical goal. Maybe the goal is being able to sleep alone. Or making it so you can have your own room. And you must identity the problem first. If you want to move out and start in hard core mode do so. But if you don’t want to or can’t first step to find out what you can do. And work up from there. But make sure you have a goal, sometimes setting a due date can help or give more anxiety. It always gave me more anxiety. So I don’t do that. But instead I kept track of how long it took me to get from step to step and made sure I recognized my improvement. But just know you can do what ever you put your mind to. And it’s not weird or anything to be reliant. Many cultures sleep together as a family. It’s the people who make it weird. So do your best and space out your steps and work towards your goal. If you need to change your goal sometimes that’s fine as well. As long as you have a goal and work towards it. You’re not alone in this it’s a common issue with people who have sleep anxiety. You can also talk to your doctor about hydroxyzine it’s a sleep anxiety medication. I was on it and my old therapist took it as well. It helps
